4(-6)-5y=1
-24-5y=1
Minus 1 on both sides
-25-5y=0
Plus 5y
-25=5y
Divide by 5 on both sides
y=-5

Answer:

y = -5

Step-by-step explanation:

To solve by using substitution, first substitute x for -6 in the equation 4x-5y=1

4(-6)-5y=1 start by simplifying this problem

-24-5y=1 now you can solve for y, add 24 on both sides

-5y=25 now divide -5 on both sides

y= -5
