The answer is 37. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
if x2 + 7 = 37, then x2 = 29 and x = ±√29
7 times 37 and 37 plus 37 plus 37 plus 37 plus 37 plus 37 plus 37 are the same value: 259

29/37 is in its lowest terms
1 with 29 remaining 66 - 29 = 37 = 1 x 37
764 Plus 37 is 801
85 plus 37 = 122
89 plus 43 plus 37 equals 169.
The LCM is 19314.
