Solve for x:
x + 2 = -11 - 2 x
Add 2 x to both sides:
2 x + x + 2 = (2 x - 2 x) - 11
2 x - 2 x = 0:
2 x + x + 2 = -11
x + 2 x = 3 x:
3 x + 2 = -11
Subtract 2 from both sides:
3 x + (2 - 2) = -11 - 2
2 - 2 = 0:
3 x = -11 - 2
-11 - 2 = -13:
3 x = -13
Divide both sides of 3 x = -13 by 3:
(3 x)/3 = (-13)/3
3/3 = 1:
Answer: |x = (-13)/3 =-4 1/3
