3(r+2s)=2t-4
a⋅(b-2)=3b
3(r+2s)=2t-4
a⋅(b-2)=3b

Question

$$-5x+3=2x+10$$

Answer

x=-1

Solution


Add \(5x\) to both sides.
\[3=2x+10+5x\]
Simplify  \(2x+10+5x\)  to  \(7x+10\).
\[3=7x+10\]
Subtract \(10\) from both sides.
\[3-10=7x\]
Simplify  \(3-10\)  to  \(-7\).
\[-7=7x\]
Divide both sides by \(7\).
\[-1=x\]
Switch sides.
\[x=-1\]
