Answer:

x=7 y=1

Step-by-step explanation:

2x-8y=6--(1)

4x+2y=30---(2)

multiply the first eq. to make the coefficients of x equal in both sides.

2×(2X−8y=6)

then we get,4X−16y=12---(3)

we can eliminate x by---> (2)-(3)

4x+2y-4x+16y=18

so we get 18y=18

y=1

sub for (1)

2x-8(1)=6

2x=14

x=7

therefore we get y=1 and x=7

hope this helps ya :)
