2X + 6 +2X +7 – X = 22

3X + 13 = 22

3X + 13 - 13 = 22 - 13

3X = 9

3X/3 = 9/3

X = 3

2x + 6 + 2x + 7 - x = 22

4x - x + 13 = 22

3x + 13 = 22

3x = 9

x = 3.

2x+6+2x+7-x = 22

First, you simplify (collect like terms)

3x+13=22

3x = 9 (Need to get rid of the "+13" so we take away 13 from both sides)

x=3 (divide both sides by 3, to get x on its own)

:)

3x+13=22

3x=9

x=3
