You solve it like this: 7x=4x-6 (subtract 4x from both sides) 3x=-6 (divide both sides by 3) x=-2
Subtract by 7x and divide by 2.
7x = 3x - 12 4x=-12 x=-3
7x + 6 - 4x = 5 + 2x + 7 subtract 6 from both sides and combine the 5 and 7 on the right: 7x - 4x = 2x + 6 subtract 2x from both sides and combine the 7x and -4x on the left: x = 6
7x = 4x - 93x = -9x = -3
