2x - 11 = -22

OpenStudy (anonymous):

hold on

OpenStudy (anonymous):

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

ah ok

OpenStudy (anonymous):

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
