6x-20 = 8x 6x-8x = 20 -2x = 20 x = -10
To solve this equation, we will first subtract 2x from each side:8x=2x+6 (8x minus 2x=6x)6x=6Now, to isolate x, we must divide out the 6:6x=6 (6x divided by 6= x)x=1If 8x=2x+6, x=1
2x+6x=-9 => 8x=-9=> x=-8/9
8x+39 = 2x-15 6x = -54 x = -9
6x = 8x+28 6x-8x = 28 -2x = 28 x = -14
