X=-1/2 because slope of another line has to perpendicular to the other one, it is the opposite and reciprocal
<span />
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!
