Use the substitution method to solve the system x=y−4, x+8y=2

First, we'll use the first equation to substitute for x in the second equation:

y-4 + 8y = 2

Combining like terms:

9y - 4 = 2

Adding 4 to both sides:

9y = 6

Dividing by 9:

y = 2/3

Now that we have found the value of y, we can substitute it back into the first equation to solve for x:

x = 2/3 - 4
x = -11/3

Therefore, the solution to the system of equations is x = -11/3 and y = 2/3.
