what's the next step here?

If you were to use the substitution method to solve the following system,
x = y + 4,
2x - 5y = 2
the next step would be:

to multiply the top equation by - 2
to add the top equation to the bottom
to solve the top equation for y
2(y + 4) - 5y = 2

collect the y on the LHS and all else on the RHS

-3y = -6 so y = ?

2(y + 4) - 5y = 2 <-- You substitute y+4 for x
