12x + 31 = 2x + 1710x = -14x = - 1.4
2x + 5 = 31 2x = 31 - 5 = 26 x = 13
3x
2x+32 = 1 2x = 1-32 2x = -31 x = -15.5
if: 2x + 6 = -6 then: 2x = -12 x = -6 if: 5x + 7y = 1 then: 5(-6) + 7y = 1 7y = 31 y = 31/7
This is only true if x = -31.
The mathematical statement 31 plus 21 equals 52 as a total.
62
-31 + 25 = 6
6x - 2x - 3 = 31 grouping the expressions with x: 6x - 2x = 31 + 3 simplifying: 4x = 34 solving for x x = 34/4 = 8.5
it equals 283. (:
25 times 31 equals 775.
