3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
3x=2x-12x=-12
dy/dx = 3 integral = (3x^2)/2
15x minus 8=minus 180 3x+8=24
3x-y=9 y=3x-9

5*2-3x-1 = 0 10-3x-1 = 0 -3x = 1-10 -3x = -9 x = 3
7
An equation where x equals 3.
3x+7=2x-5 x=-12
2x+3y=13 3x-y=3 x=2
6x-3x =6 3x=6 so 6 divided by 3 = 2
