-(1 + 7x) - 6(-7 - x) = 36

Simplify.

-1 - 7x + 42 + 6x = 36

Add 1 to both sides.

-7x + 42 + 6x = 36 + 1

Simplify.

-x + 42= 37

Subtract 42 from both sides.

-x = 37 - 42

Simplify.

-x = -5

Divide both sides by -1.

x = 5

~Hope I helped!~

-(1 + 7x) - 6(-7 - x) = 36
-1(1+7x) - 6(-7 - x) = 36
-1 - 7x + 42 + 6x = 36
41 - x = 36
41 = 36 + x
5 = x
