6 + 2x = x - 6 2x - x = -6 -6 x = -12
6 is a digit . 2x is a variable. Therefore, you don't have an answer for 6+2x. You may ask "what is x if 6+2x=12?" 6+2x=12 Subtract 6 from both sides 2x=6 divide both sides by 3 x=2
6 + 2x = x - 6 6 + x = -6 x = -12
2x-6=4 6+4=2x 10=2x 10/2=x 5=x x=5
If: y = x+6 and y = 2x Then: x+6 = 2x And: 6 = 2x-x => 6 = x So: x = 6 and y = 12
2x - 6 = x + 5 Isolate x. 2x - x = 6 + 5 x = 11

-3x + 2x > 6 -x > 6 x < 6 {x| x < 6 } or ( -∞, 6)
2x-6=x+5 2x -x=6+5 x=11 Check the math.
