8(p-2) = 32
8p - 16 = 32
+16 on each side
8p= 48
Divide by 8 on each side
P= 6
2^3 * 2^-5 = 2^(3 + (-5) = 2^(3 - 5) = 2^-2
X is 6 that is the missing value in the equation
Since the two measures are vertical angles, you want to set them equal to each other :
6x+7=8x-17
-6x -6x
——————
7=2x-17
+17 +17
———————
24= 2x
X= 12
———
The answer is 12.
