Add 4x + 2x = 6x + 4 = 6x + 4
You did not state the operation: add or subtract. Is it 2x + 3 + 4 = 17? Is it 2x - 3 + 4 = 17?
2x + 8 = 3x - 4 Subtract 2x from both sides: 8 = x - 4 Add 4 to both sides: 12 = x
2x-4=6 add four to each side. That gives you 2x=10 divide by 2 x=10/2 or 5.
2X - 4 = - 10 add 4 to each side 2X - 4 + 4 = - 10 + 4 2X = - 6 divide each side by 2 X = - 3 check in original equation 2(-3) - 4 = - 10 - 6 - 4 = - 10 - 10 = - 10 checks
