How do I solve the following by substitution:
5x -2y =-5
y - 5x = 3

8x - 4y = 16
y = 2x - 4

4x -12y =5
-x + 3y = -1

5x -2y =-5
y - 5x = 3

5x -2y =-5
-5x +y = 3

5x -2y =-5
10x -2y =-6

15x =-1

x= -1/15

(-1/15x5) -2y =-5

-1/3 -2y=-5
+1/3 +1/3

-2y= 4 2/3
/-2 /-2

y= -2 1/3





x= -1/15
y= -2 1/3
