Question

Find the value of x that will make A||B
9x + 4
5x + 20
x = [?]

Answer 1

142 is x

Explanation:

by creatin the inequality 14x+24=180 we know that and straight line is 180 degrees and 14x is 9x+5x and 24 is 20 +4. we can now solve by doing the following below:

14x+24=180

-24 | -24

180-24=156

bring down the 14x now we have

14x=156

-14 | -14

156-14 is 142 so x=142

Answer 2

9x + 4= 5x + 20 (alternate interior angles)

9x-5x =20-4

4x = 16

x= 16/4

x= 4
