-2x+14=20 -2x=20-14 -2x=6 -2x/-2=6/-2 x=-3
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
2x+1 = 9 2x = 9-1 2x = 8 x = 4
8x + 2 = 6x + 10 Subtract 6x from both sides: 2x + 2 = 10 Subtract 2 from both sides: 2x = 8 Divide by 2: x = 4 x = 4
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
