3x = 6x - 15
Add 15 to each side:
3x + 15 = 6x
Subtract 3x from each side:
15 = 3x
Divide each side by 3:
5 = x
Add 8 to each side:

6x - 12 = 3x + 15 3x = 27 x = 9
3x equals 6x-15 then x plus 8 equals?
3x=6x-15 ....you want to take 6x and put it on the other side of the = sign. To do that you do the opposite. So you would subtract since 6x is a positive number. so then the equation is 3x-6x=-15. 3x-6x = -3x which makes the equation -3x=-15. Then you would take -3 which is being multiplied by x and do the opposite operation on the other side. so -3 divided by -15 equals 5. which makes the equation now x=5. So then 5+8=13
What is the answer to 4 plus 6x equals 5 plus 3x plus 7?
