Answer:

[tex]\bold{x=2}[/tex]

Step By Step Explanation:

Expand [tex]\bold{2.5\left(6x-4\right): \ 15x-10}[/tex]

Expand [tex]\bold{10+4\left(1.5+0.5x\right): \ 2x+16}[/tex]

[tex]\bold{15x-10=2x+16}[/tex]

Add 10 To Both Sides

[tex]\bold{15x-10+10=2x+16+10}[/tex]

Simplify

[tex]\bold{15x=2x+26}[/tex]

Subtract 2x From Both Sides

[tex]\bold{15x-2x=2x+26-2x}[/tex]

Simplify

[tex]\bold{13x=26}[/tex]

Divide Both Sides By 13

[tex]\bold{\frac{13x}{13}=\frac{26}{13}}[/tex]

Simplify

[tex]\bold{x=2}[/tex]
