x=4/3
What is the answer to 4 plus 6x equals 5 plus 3x plus 7?
6x+4=3x+12 => 6x-3x=12-4 => 3x=8 => x=8/3=2.666...
3x plus 5 equals 6x plus 23 what is x?
3x + 5 = 6x + 23 -3x = 18 x = -6
WHAT DOES 100 equals 3x plus 6x plus 10 equals?
x=10
2x-6x plus 3x equals -41?
2x - 6x + 3x = -412x - 3x = -41-1x = -41x = 41
6x plus 11 equals 3x plus 15?
x=4/3
What is 9x plus 6 equals 6x plus 15?
9x+6 = 6x+15 9x-6x = 15-6 3x = 9 x = 3
6x-12 equals 3x 15?
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
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
What is the answer to 4 plus 6x equals 5 plus 3x plus 7?

What does 3x plus 42 equals 6x plus 12 mean?
3x+42=6x+12 42=6x-3x+12 42=3x+12 42-12=3x 30=3x 10=x
What is x if 3x plus 50 equals 6x plus 14?
3x+50=6x+14 50-14=6x-3x 36=3x x=36 / 3 therefore x=12
