x=-24
If: x+3+6x+9 = 0 then 7x+12 = 0 So: 7x = -12 and x = -12/7
no...why would it.... it equals 2x+9
-9
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
-12 = x+9 x+9 -9 = -12 -9 x = -21
x=-24
If: x+3+6x+9 = 0 then 7x+12 = 0 So: 7x = -12 and x = -12/7
no...why would it.... it equals 2x+9
-9
-10x+3 = -x+12 -10x+x = 12-3 -9x = 9 x = -1
6 + 9 + 12 x 5 = 75 (The multiplication is done first)

12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 + 12 = 108 The explanation is very simple. Since there is nine twelves you are technically repeating twelve nine times, and the operation for that equation would be multiplication. The equation would be- 12x9= 108
