8. Solve for "x":
(5x + 2)
(x + 4)

Answer:
x = 29
Step-by-step explanation:
(5x + 2) + (x + 4) = 180
6x + 6 = 180
6x = 174
x = 29

Answer:
x=29 degrees
Step-by-step explanation:
We know that the straight line is 180 degrees because definition of a straight. So we take 4 and 2 and subtract them off of 180. so 180-4-2=174. Now, we do 174/6 because you want to figure out how much times 6 can go into 174 because there are 6 x's (if that makes sense). So we get the answer 29 so x=29 degrees.
Basically, you want to combine like terms. So we combined the non-variable numbers and we subtract it off of 180. Then we take the variables and combine them. So in this case, it would be x+5x=6x. Then we need to figure out what x is so we just divide by 6 on both sides. So 6x=174 so x=29.
I hope this made sense.
