Answer:
x=4,y=-6
Step-by-step explanation:
2x-4y=32 ――――equ 1
7x+6y=-8 ――――equ 2
multiply equ 1 by 6 which is the co-efficient of y in equ 2, so vice verser for equ 2
2x-4y=32 ――――equ 1 multiply 6
7x+6y=-8 ――――equ 2 multiply 4
12x-24y=192
28x+24y=-32
40x=160
x=4 ――――equ 3
so put 4 in x in any equation but i choose equ 1
2x-4y=32
2（4）-4y=32
8-4y=32
collect like term
-4y=32-8
-4y=24
y=-6
