Question

I need help with this math​

Answer 1

Answer:

x=9  y=-4

Step-by-step explanation:

1) to eliminate a variable make sure they are the same so you can cancel them out

lets eliminate x

-3 and -2 share a GCF of 6 so

2(-3x-4y=-11)

-6x-8y=-22

3(-2x-6y=6)

-6x-18y=18

-6x-8y=-22

-

-6x-18y=18

--------------------------

10y=-40

y=-4

2)substitute y as -4 in the second equation

-2x-6(-4)=6

-2x+24=6

-2x=-18

x=9

Answer 2

Answer:

(9,-4)

Step-by-step explanation:

$(-3x-4y=11)*-2(-2x-6y=6)*3\\6x+8y=22-6x-18y=18\\ 6x and -6x cancel out-10y=40 y=-4 \\Plug -4 for y. -2x-6(-4)=6 -2x+24=6 -24 -24 -2x=-18 x =-9$
