1.  x=9

2  x=9

3  x=10

4   x=7

Step-by-step explanation:

1. 15+5x + 14x-6 = 180   supplementary angles

combine like terms

9 + 19x = 180

subtract 9 from each side

19 x = 171

divide by 19

19x/19 = 171 /19

x = 9

2. 13x-7 = 11x+11   corresponding angles are equal

subtract 11x from each side

2x -7 = 11

add 7 to each side

2x = 18

divide by 2

x =9

3.  x+ 100 = 90  alternate interior angles are equal

subtract 100 from each side

x = -10

4.  17x+1 = 120   alternate exterior angles are equal

subtract 1 from each side

17x = 119

divide by 17 on each side

x = 119/17

x=7

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
