2x + 5 = 13 2x = 8 2x/2 = 8/2 x=4

2x+2=x+5 x=3

Simplify 4x + 3 = 2x + 8 2x = 5 x =2½

-5, 1/2

2x + 2 = 3x - 57 = x

X equals 2 :)

4x + 2 = 2x + 5 Subtract through by 2x 2x + 2 = 5 Subtract through by 2 2x = 3 Divide through by 2 x = 1.5 ■

x= -5

5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2

2x+3 = 3x+5 2x-3x = 5-3 -x = 2 x = -2

6x + 3 = 2x + 5 4x = 2 x=1/2

x = 2

X=27

4x + 1 = 2x + 5 4x + 1 - 2x = 2x + 5 - 2x 2x + 1 = 5 2x + 1 - 1 = 5 - 1 2x = 4 2x/2 = 4/2 x = 2

2x + 1 = 6 2x = 5 x = 5/2 or 2.5

That's not real clear. It could be 2 times positive 1 (which is 2) plus 5, which equals 7. It could be 2x + 1 + 5 which equals 2x + 6 It could be 2x + 1 = 5, in which case x = 2

2x + 2 = x + 5Subtract 2 from each side:2x = x + 3Subtract 'x' from each side:x = 3

If: x+1+2x = 1x+5 Then: x = 2

3x + 2 + 2x = 7; 3x + 2x = 5x, so 5x + 2 = 7; 7-2=5, so 5x=5. 5x divided by 5 and 5 divided by 5 equals 1, so x equals 1.

2x + 5 = 13 2x = 8 x = 4

2x-4

(-5, 2)

2x-3=x+2 2x-x=2+3 x=5

3 = 2x + 5 -5 -5 -2 = 2x ---------- 2 x = -1

yes. its 2! :)
