5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
x= -5
3x+8 = 2x+5 Subtract 2x from both sides: x+8 = 5 Subtract 8 from both sides: x = -3
-2x+5=13 you subtract 5 away from +5 and this cancels out. you then do the same to the other side by taking 5 away from 13 therefor you get 8. Now you have -2x=8, take -2x and divide it into 8 and you get 4.

2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4
6x - 8 + 2x - 5 = 7 - 2x ?
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
2x-3 = x+5 2x-x = 8 x = 8
x=5
3x+5 = 2x+13 3x-2x = 13-5 x = 8
x= -5
3x+8 = 2x+5 Subtract 2x from both sides: x+8 = 5 Subtract 8 from both sides: x = -3
-2x+5=13 you subtract 5 away from +5 and this cancels out. you then do the same to the other side by taking 5 away from 13 therefor you get 8. Now you have -2x=8, take -2x and divide it into 8 and you get 4.
6x-8+2x-5 = 7-2x 6x+2x+2x = 7+8+5 10x = 20 x = 20/10 x = 2
