Answer: 20

86 - x - 49 = 14          Simplify
-x + 37 = 17               Subtract 37 from both sides
-x = -20                      Divide -1 from both sides
x = 20                        Answer!
Your gonna add 86 and 49. And the result is 135. You want something that will give you 14. So you subtract 14 from 135 and that will give you 121. And 121 is your answer
