Kelsie Graham · Answer 1

x=8 and y=2

Step-by-step explanation:

x+y=10

x=4y

x+y=10

4y+y=10

5y=10 (divide both sides by 5)

y=2

x=4y=4*2=8

Keely Matthews · Answer 2

2 and 8.

Step-by-step explanation:

y = - x + 10

y = 4x

If we subtract we eliminate y:

0 = - x + 10 - 4x

0 = - 5x + 10

5x = 10

x = 2.

and y = 4 * 2 = 8.
