Answer:

9x-3=7x+21

9x=7x+24

2x=24

x=12

Explanation:

(9x-3) and (7x+21) are corresponding angles that means that they are congruent. So they equal each other.

Answer:

X = 12

Explanation:

Since each angle is equivalent to each other, you can write the equation:

(9x-3) = (7x+21)

Then Simplify.

Subtract both sides by 7x

2x-3=21

Add 3 To Both Sides

2x=24

Divide by 2

X = 12
