x = 86

y = 94

Step-by-step explanation:

The angle that measures 86 degrees and x are alternate exterior angles, which means they're equal.

The 86 degree angle and y add up to 180 degrees, since the lines are parallel. So,

180 - 86 = 94

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
