Question

x - y = -2
2x + 4y = 38​

Answer 1

Answer:

y=7

x=5

Step-by-step explanation:

x-y=-2

 +y   +y

x=-2+y

then substitute -2+y into the x in the other equation

so:

2(-2+y) + 4y = 38

-4+ 2y +4y = 38

-4+6y= 38

+4         +4

6y=42

divide both sides by 6

y=7

to get X:

x-y=-2

x-(7)=-2

 +7   +7

x=5
