12x - 66 = 3x + 9
12x - 3x = 9 + 66
9x = 65
x = 7.22
Check:
12(7.22) - 60 + 6 = 1(7.22) + 9 + 2(7.22)
86.64 - 66 = 7.22 + 9 + 14.44
20.64 = 30.66

2x plus 2 equals x plus 6?
2x+2=x+6 first subtract 2x. -2x -2x2=-1x+6 then subtract 6-6 -6-4=-1x finally divide by -1x=4 X equals four.
2x-6x plus 3x equals -41?
2x - 6x + 3x = -412x - 3x = -41-1x = -41x = 41
How do you solve x plus 6 equals 2x-9?
x + 6 = 2x - 9 Add 9 to both sides: x + 15 = 2x Subtract 1x from both sides: 15 = 1x or 15 = x
What is X 2x-1 equals -3?
2x-1=-32x=-3+1x=-2/2x=-1
2X plus 2X plus 9X equals?
it equals 13X.
2X plus 1 equals 1X plus 11?
2x + 1 = 1x + 11Subtract 1x from each side:1x + 1 = 11Subtract 1 from each side:1x = 10

1x + 5
2X plus 2X plus 9X equals?
it equals 13X.
What does x plus x equal?
There is always a 1 in front of the x but the 1 is invisible so it same as 1x + 1x = 2x x + x = 2x
