Question

Given m || n, find the value of x.

Answer 1

x = 11

Explanation:

Since it's given n || m, we can write the following equation to find the value of x:

9x - 3 = 7x + 19 because these two are alternate exterior angles and have equal angle measurement.

• transfer like terms to the same side of the equation

9x - 7x = 19 + 3

• add/subtract terms

2x = 22

• Divide both sides by 2

x = 11
