Help ASAP. Solve both

Answer 1

Step-by-step explanation:

question 15

For y to be parallel to z the sum of given angles must be equal to 180°

3x + 7 + 10x - 22 = 180° add like terms

13x - 15 = 180 add 15 to both sides

13x = 195 divide both sides by 13

x = 15

question 16

If y is parallel to z then the given angles are alternate exterior and has same measurement

11x - 3 = 4x + 39

11x - 4x = 39 + 3

7x = 42 divide both sides by 7

x = 6
