By elimination method, subtracting 2 from 1
x-7y=-42
x-3y=6
so,4y=-48
y=-12
4
putting y =-12 in 2
x-3(-12)=6
x+36=6
x=6-36
x=-30
x-7y=-42
x-3y=6
so,4y=-48
y=-12
4
putting y =-12 in 2
x-3(-12)=6
x+36=6
x=6-36
x=-30

by subtracting 2nd equation from 1st equation, we get -4y + 48 = 0
by solving, we get y = -12
by substituting y value, we get x = 42
