X+4y =6 x-4y=19solve systems of linear equations by substitution show your work

I putted those equations into order , first I putted on the top the second equation on the bottom, this will help u to find out the difference between them. I did subtraction first , so 4y-(-4y) = 8y , then 6 -19=-13. After u do ur divine u will get Y= -13/8
