To solve the equation -3 + 3x + 6x = 15, combine like terms: 9x - 3 = 15. Then, add 3 to both sides: 9x = 18. Finally, divide both sides by 9 to solve for x: x = 2.

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

If 3x equals 6x- 15 then x plus 8 equals?

3x = 6x - 15Add 15 to each side:3x + 15 = 6xSubtract 3x from each side:15 = 3xDivide each side by 3:5 = xAdd 8 to each side:13 = x + 8
