Answer:

$\boxed{\bold{x=-\frac{7}{3}}}$

Step-by-step explanation:

Expand: $\bold{5\left(2x\right): \ 10x}$

Expand: $\bold{7\left(x-1\right): \ 7x-7}$

$\bold{10x=7x-7}$

Subtract 7x From Both Sides

$\bold{10x-7x=7x-7-7x}$

Simplify

$\bold{3x=-7}$

Divide Both Sides By 3

$\bold{\frac{3x}{3}=\frac{-7}{3}}$

Simplify

$\bold{x=-\frac{7}{3}}$
