7 x 51=357
357-45-49-58-53-58-51=43

(45+49+58+53+58+51+x)/7 = 51
Add numbers on left
Multiply both sides times 7 (on the left 7/7 cancel each other)
Subtract what you get from both sides, you will be left with x on the left and the answer you are looking for on the right. You should get 43, use your calculator.
