Answer:

[tex]x=12[/tex]

Step-by-step explanation:

we have

[tex]-8(8-x)=\frac{4}{5}(x+28)[/tex]

solve for x

Applying distributive property both sides

[tex]-8(8)-8(-x)=\frac{4}{5}(x)+\frac{4}{5}(28)[/tex]

[tex]-64+8x=\frac{4}{5}(x)+\frac{112}{5}[/tex]

Multiply by 5 both sides to remove the fractions

[tex]-64(5)+8x(5)=4x+112[/tex]

[tex]-320+40x=4x+112[/tex]

subtract 4x both sides

[tex]-320+40x-4x=4x+112-4x[/tex]

[tex]-320+36x=112[/tex]

Adds 320 both sides

[tex]-320+36x+320=112+320[/tex]

[tex]36x=432[/tex]

divide by 36 both sides

[tex]x=12[/tex]
