Answer

$$v=-(4*x+5)/(1.7*So*e^3*l^3*t^2*h*f*o^3*w*n^2*g*q*u*a*s*x)$$

Solution


Regroup terms.
\[1.7lllvtthfooownngquasxSoee\imath e\imath -5=2x\times 2\]
Simplify  \(1.7lllvtthfooownngquasxSoee\imath e\imath \)  to  \((1.7){l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasxSoee\imath e\imath \).
\[1.7{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasxSoee\imath e\imath -5=2x\times 2\]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[1.7{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasxSo{e}^{3}{\imath }^{2}-5=2x\times 2\]
Use Square Rule: \({i}^{2}=-1\).
\[1.7{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasxSo{e}^{3}\times -1-5=2x\times 2\]
Simplify  \(1.7{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasxSo{e}^{3}\times -1\)  to  \((-1.7){l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasxSo{e}^{3}\).
\[-1.7{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasxSo{e}^{3}-5=2x\times 2\]
Regroup terms.
\[-1.7So{e}^{3}{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasx-5=2x\times 2\]
Simplify  \(2x\times 2\)  to  \(4x\).
\[-1.7So{e}^{3}{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasx-5=4x\]
Add \(5\) to both sides.
\[-1.7So{e}^{3}{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasx=4x+5\]
Divide both sides by \(-1.7\).
\[So{e}^{3}{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasx=-\frac{4x+5}{1.7}\]
Divide both sides by \(So\).
\[{e}^{3}{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasx=-\frac{\frac{4x+5}{1.7}}{So}\]
Simplify  \(\frac{\frac{4x+5}{1.7}}{So}\)  to  \(\frac{4x+5}{1.7So}\).
\[{e}^{3}{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasx=-\frac{4x+5}{1.7So}\]
Divide both sides by \({e}^{3}\).
\[{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasx=-\frac{\frac{4x+5}{1.7So}}{{e}^{3}}\]
Simplify  \(\frac{\frac{4x+5}{1.7So}}{{e}^{3}}\)  to  \(\frac{4x+5}{1.7So{e}^{3}}\).
\[{l}^{3}v{t}^{2}hf{o}^{3}w{n}^{2}gquasx=-\frac{4x+5}{1.7So{e}^{3}}\]
Divide both sides by \({l}^{3}\).
\[v{t}^{2}hf{o}^{3}w{n}^{2}gquasx=-\frac{\frac{4x+5}{1.7So{e}^{3}}}{{l}^{3}}\]
Simplify  \(\frac{\frac{4x+5}{1.7So{e}^{3}}}{{l}^{3}}\)  to  \(\frac{4x+5}{1.7So{e}^{3}{l}^{3}}\).
\[v{t}^{2}hf{o}^{3}w{n}^{2}gquasx=-\frac{4x+5}{1.7So{e}^{3}{l}^{3}}\]
Divide both sides by \({t}^{2}\).
\[vhf{o}^{3}w{n}^{2}gquasx=-\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}}}{{t}^{2}}\]
Simplify  \(\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}}}{{t}^{2}}\)  to  \(\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}}\).
\[vhf{o}^{3}w{n}^{2}gquasx=-\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}}\]
Divide both sides by \(h\).
\[vf{o}^{3}w{n}^{2}gquasx=-\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}}}{h}\]
Simplify  \(\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}}}{h}\)  to  \(\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}h}\).
\[vf{o}^{3}w{n}^{2}gquasx=-\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}h}\]
Divide both sides by \(f\).
\[v{o}^{3}w{n}^{2}gquasx=-\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}h}}{f}\]
Simplify  \(\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}h}}{f}\)  to  \(\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf}\).
\[v{o}^{3}w{n}^{2}gquasx=-\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf}\]
Divide both sides by \({o}^{3}\).
\[vw{n}^{2}gquasx=-\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf}}{{o}^{3}}\]
Simplify  \(\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf}}{{o}^{3}}\)  to  \(\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}}\).
\[vw{n}^{2}gquasx=-\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}}\]
Divide both sides by \(w\).
\[v{n}^{2}gquasx=-\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}}}{w}\]
Simplify  \(\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}}}{w}\)  to  \(\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}w}\).
\[v{n}^{2}gquasx=-\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}w}\]
Divide both sides by \({n}^{2}\).
\[vgquasx=-\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}w}}{{n}^{2}}\]
Simplify  \(\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}w}}{{n}^{2}}\)  to  \(\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}w{n}^{2}}\).
\[vgquasx=-\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}w{n}^{2}}\]
Divide both sides by \(g\).
\[vquasx=-\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}w{n}^{2}}}{g}\]
Simplify  \(\frac{\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}w{n}^{2}}}{g}\)  to  \(\frac{4x+5}{1.7So{e}^{3}{l}^{3}{t}^{2}hf{o}^{3}w{n}^{2}g}\).
