Question

-8x-14=7(-2-4x)+4 Solve for x

Answer 1

Given :

$-8x-14=7\mleft(-2-4x\mright)+4$

Solve to find x;

$\begin{gathered} -8x-14=7\mleft(-2-4x\mright)+4 \\ -8x-14=-14-28x+4 \end{gathered}$

Combine like terms :

$\begin{gathered} -8x+28x=-14+4+14 \\ 20x=4 \end{gathered}$

Divide both sides by 20

$\begin{gathered} \frac{20x}{20}=\frac{4}{20} \\ x=\frac{4}{20}=\frac{1}{5}=0.2 \end{gathered}$

So, the value of x = 0.2
