Can someone please answer this please ASAP

x = 10

y = 15

Step-by-step explanation:

Angles 8x - 10 and 7x are congruent because they are alternate interior angles of parallel lines cut by a transversal.

8x - 10 = 7x

x = 10

7x = 7(10) = 70

6y + 20 and 7x are supplementary since they are a linear pair.

6y + 20 + 7x = 180

6y + 20 + 70 = 180

6y = 90

y = 15

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.
