2x - 11 = -22

hold on

implifying
2x + -11 + 2x + 27 = 100
Reorder the terms:
-11 + 27 + 2x + 2x = 100
Combine like terms: -11 + 27 = 16
16 + 2x + 2x = 100
Combine like terms: 2x + 2x = 4x
16 + 4x = 100
Solving
16 + 4x = 100
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-16' to each side of the equation.
16 + -16 + 4x = 100 + -16
Combine like terms: 16 + -16 = 0
0 + 4x = 100 + -16
4x = 100 + -16
Combine like terms: 100 + -16 = 84
4x = 84
Divide each side by '4'.
x = 21
Simplifying
x = 21
x =21

what he said^ xD
OpenStudy (texaschic101):
2x + 27 + 2x - 11 + 80 = 180
4x + 96 = 180
4x = 180 - 96
4x = 84
x = 84/4
x = 21
check..
2(21) + 27 + 2(21) - 11 + 80 = 180
42 + 27 + 42 - 11 + 80 = 180
180 = 180 (correct)
so x = 21
