I'm assuming you need to evaluate/simplify the equation, so you need to isolate/get x by itself in the equation:
2(3x + 1) = 11 Divide by 2 on both sides
3x + 1 =
[11/2 or 5.5] Subtract by 1 on both sides
[make the denominator the same to combine fractions]
3x =
Divide by 3 on both sides
x =
36 - (-20) = 56
SO the number that should be added to -20 to get the answer of 36 is 56.
