Caylee Nelson · Answer 1

X = - 4y x + 5y = 2

-4y + 5y = 2

*add - 4y and 5y*

y = 2

x = - 4 (2)

*Multiply - 4 and 2*

x = - 8

Seamus Gallegos · Answer 2

Y=2, put - 4y in for do to the second equation, and then it's technically 5-4 so then you have 1y=2 then you move the 1 to the other side by dividing 2 by 1.
