-4(2x-7)=3(52-4x)

We move all terms to the left:

-4(2x-7)-(3(52-4x))=0

We add all the numbers together, and all the variables

-4(2x-7)-(3(-4x+52))=0

We multiply parentheses

-8x-(3(-4x+52))+28=0


We calculate terms in parentheses: -(3(-4x+52)), so:

3(-4x+52)

We multiply parentheses

-12x+156

Back to the equation:

-(-12x+156)


We get rid of parentheses

-8x+12x-156+28=0

We add all the numbers together, and all the variables

4x-128=0

We move all terms containing x to the left, all other terms to the right

4x=128

x=128/4

x=32
