Answer:
24
Step-by-step explanation:
3x+6=30
Get the co-efficient by itself
3x +6=30
-6. -6
3x=24
Divide by 3 on both sides
24/3
x =8
Answer:
x = 40
y = 62
Step-by-step explanation:
I figured out the answer by finding the x on the left triangle first by writing an equation:
(3x - 18) + (x + 7) + (x - 9) = 180
once I worked that I plugged in the number which was 40.
Then for the triangle to the right I also plugged in the numbers for x and got 118 degrees I took 180 and subtracted 118 to get my answer of 62 for y.
