Answer 1

x=3 y=4

Explanation:

-4x= -6y+12 -1

8x-4y = 8 -2

-4x+6y=12 -1

8x-4y = 8 -2

multiply first equation by 2:

2(-4x+6y=12)

= -8x+12y=24

add with 2nd equation;

-8x+12y=24

+

8x-4y=8

-8x+8x=0

+12-4y=8y

24+8=32

0+8y=32

y=32/8

y=4

input y into any equation to get x:

-4x= -6(4)+12

-4x = -24+12

-4x= -12

-x= -12/4

x=3
