**Answer:**

72°

**Step-by-step explanation:**

4+2+6+8=20

360÷20=18

AC=4x18=72

So you need to isolate the variable in order to get your answer. This is how you do it.

3x + 5 = 2x - 7

Subtract 2x from both sides.

1x + 5 = -7

Subtract 5 from both sides to have the variable by itself.

1x = -12

Divide 1 to both sides to find the value of x.

x = -12

Now we need to check.

3(-12) + 5 = 2(-12) - 7

-36 + 5 = -24 - 7

-31 = -31

Since both sides or the same you now know that -12 is the solution.

I hope this helps love! :)
