-20x+40=2(14-6x)+5x

We move all terms to the left:

-20x+40-(2(14-6x)+5x)=0

We add all the numbers together, and all the variables

-20x-(2(-6x+14)+5x)+40=0

We calculate terms in parentheses: -(2(-6x+14)+5x), so:We get rid of parentheses

2(-6x+14)+5x

We add all the numbers together, and all the variables

5x+2(-6x+14)

We multiply parentheses

5x-12x+28

We add all the numbers together, and all the variables

-7x+28

Back to the equation:

-(-7x+28)

-20x+7x-28+40=0

We add all the numbers together, and all the variables

-13x+12=0

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

-13x=-12

x=-12/-13

x=12/13
