Example

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

Question

$$4=-2(x+3)$$

Answer

x=-5

Solution


Divide both sides by \(-2\).
\[-\frac{4}{2}=x+3\]
Simplify  \(\frac{4}{2}\)  to  \(2\).
\[-2=x+3\]
Subtract \(3\) from both sides.
\[-2-3=x\]
Simplify  \(-2-3\)  to  \(-5\).
\[-5=x\]
Switch sides.
\[x=-5\]
