Answer:

[tex]\boxed{\bold{x=-\frac{7}{3}}}[/tex]

Step-by-step explanation:

Expand: [tex]\bold{5\left(2x\right): \ 10x}[/tex]

Expand: [tex]\bold{7\left(x-1\right): \ 7x-7}[/tex]

[tex]\bold{10x=7x-7}[/tex]

Subtract 7x From Both Sides

[tex]\bold{10x-7x=7x-7-7x}[/tex]

Simplify

[tex]\bold{3x=-7}[/tex]

Divide Both Sides By 3

[tex]\bold{\frac{3x}{3}=\frac{-7}{3}}[/tex]

Simplify

[tex]\bold{x=-\frac{7}{3}}[/tex]
