3x + 9 = 44 - 2x (add 2x to each side)
5x + 9 = 44 (minus 9 from each side)
5x = 35 (divide each side by 5)
x = 7

3 x + 9 = 44 - 2 x
subtract 9 from both sides:
3 x + 9 - 9 = 44 - 2x - 9
3 x = -2 x +35
Add 2 x to both sides:
3 x + 2 x = -2 x + 35 + 2 x
5 x = 35
Divide both sides by 5 :
5x / 5 = 35/ 5
x = 7
hope this helps!
