3x+2y= -26/×3
2x-6y= -10

9x+6y= -78 (I)
2x-6y=-10 (II)

I+II => 11x= -88
x= -88/11
x= -8

2x-6y= -10
2×(-8) -6y= -10
-16 -6y= -10
-6y= -10+16
-6y= 6
y= 6/-6
y= -1

If you have any questions feel free to ask!I hope I helped :)

3x + 2y = -26 turns into


y = [tex]\frac{-3x}{2}[/tex] - 13


2x - 6y = -10 turns into


y = [tex]\frac{1x}{3}[/tex] + [tex]\frac{5}{3}[/tex]


and you would put that into the solution.


I hope this helped!
