Plug it in:
3x + 6(3) = 24
3x + 18 = 24
Then subtract both sides by 18:
3x + 18 - 18 = 24 - 18
3x = 6
Then, divide both sides by 3
3x/3 = 6/3
Simplify,
x = 2
Answer:
None.

Hi!!
A triangle has <u>NO</u> parrallel lines. It cannot. Think of a triangle. IF it had a parralell line(s), it would not have 3 sides.

Hope this helps!

(X+12) + 140 = 180
X + 12 + 140 = 180
X + 152 = 180
X = 180 - 152
X = 28
