please show explanation
this is 15 points

Answer 1

hope this helps!!

Explanation:

Answer 2

y=-4, x=-3

Explanation:

1. Find x in terms of y

x-6y=21

x=21+6y

2. Substitute the x value for the y equivalent of x times the coefficient (6)

6(21+6y)+2y=-26

3. Distribute and simplify

126+36y+2y=-26

126+38y=-26

-152=38y

y=-4

3. Find x using the y value. Substitute y with -4

x-6(-4)=21

x+24=21

x=-3
