44 + 555 + 211 = 810
The sum is: 22+212+211 = 445
1 + 211 = 212
37 + 142 = 179
6489+211=6700
7*8+(1/5)*20+211 = 7*8+4+211 = 56+4+211 = 271
(7 × 5) + 142 = 177
1 + 210 = 211
59 + 61 + 67 + 71 + 73 + 79 + 83 + 89 + 211 = 793

The question is the equivalent to asking for the solution to the equation: 149 + x = 211 (solve for x) It is 149 plus 62 = 211, i.e. x = 62
X 3 plus x-142 plus x is an equation equal to x3+2x-142.
