Answer:
x = 32
Step-by-step explanation:
Add 7 to both sides
Simplify
-7 + 7 = 0 and 1 + 7 = 8 because of this now
Square both sides
2x = 64
Slove 2x = 64
64 ÷ 2 = 32 = x
Answer:234 inches.
Step-by-step explanation:
First you have to get x
5x-21=2x-6
3x=15
x=5
then substitute in any of the equations with x to get the y value:
y=2x-6
y=2(5)-6
y=4
so the answer is choice B
