X + 6 = 2Xsubtract X from each sideX - X + 6 = 2X - X6 = X========check in original equation(6) + 6 = 2(6)12 = 12========checks
-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3
2x-11
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
4x+35-2x+25 = 6 2x+60 = 6 2x = 6-60 2x = -54 x = -27

8x-7 plus 2x equals 6 plus 5x plus 2?
-2x-6= -2x-6Another answer:-2x-6 = 2x+6-2x-2x = 6+6-4x = 12x = -3

2x+2=x+6 first subtract 2x. -2x -2x2=-1x+6 then subtract 6-6 -6-4=-1x finally divide by -1x=4 X equals four.

6 + 2x = 5x + 9 , 6 - 9 = 5x - 2x , -3 = 3x , x = -1
22+2x = 37+6+x 2x-x = 37+6-22 x = 21
