Hello!
We will put the x value into the second equation and solve below.
2(-3y-13)+2y=-6
-6y-26+2y=-6
-4y-26=-6
-4y=20
y=-5
We will know put our y value into the first equation to find x.
x==-3(-5)-13
x=15-13
x=2
Just to check we will put our two values into the second equation and see if it is true.
4+-10=-6
-6=-6
----------------------------------------------------------

I hope this helps!
