6x-2y=-18

Answer 1

4x+5y=7....(i)
6x-2y=-18...(ii)
I'll show u using elimination method
u multiply equation (i) by 3
u multiply equation (ii) by 2
12x+15y=21
-)12x-4y=-36
-----------
0 + 19y=57
19y=57
y=3

Answer 2

plug y back in any equation u get -2

Answer 3

for example
4x=7-5(3)
4x=-8
x=-2

Answer 4

so would the answer be 19y=57
y=3
