Answer:

x = 6

y = -4

Explanation:

Comment

You have 2 equations

x = 6

4x + y = 20

You already know what x is from the first equation.

All you need do is put 6 in for x in the second equation.

Solution

x = 6

4*6 + y = 20 Combine what you can on the left

24 + y = 20 Subtract 24 from both sides

24-24+ y = 20-24 Combine

y = - 4
