-6a + 8 = 2 -6a = -6 a = 1
If you mean: 15a = 6a - 90 then the variable a works out as -10. If you mean 15a + 6a - 90, then it equals 21a - 90.
6a + 4 = 5a - 2 means that 6a - 5a = -2 - 4 which gives a = -6

6a + 9 = ? a = 7 just replace a with 7 6(7) + 9 order of operations; multiply first 42 + 9 = 51
If 6a divided by 2 equals 12 then A equals
-6a + 8 = 2 -6a = -6 a = 1
5a+5=6a-7
If you mean: 15a = 6a - 90 then the variable a works out as -10. If you mean 15a + 6a - 90, then it equals 21a - 90.

6a - 13 = -5 Therefore, 6a = 8 a = 8/6 a = 1.3 recurring (that is, 1.3333..)
If 6A - 58 = 44 then 6A = 102 making A = 17.
6a + (7b - 4a - 8b) = (6a - 4a) + (7b - 8b) = 2a - b
6a - 4 = -2(+ 4 on both sides)6a = 2(divide both sides by 6)a = 2/6a = 1/3
6a-3=8a+11 -3-11=8a-6a -14=2a a=-7
