April wants to prove that she can solve the system of equations using the substitution method.
3x + y = 8
y = 4x - 6

Which equation shows the first step in solving the system of equations using the substitution method?
Options: 7x + 2y = 2, -x +2y = 2, 3x + (4x-6) = 8, 3(4x-6) +y = 8

Back

3x + (4x-6) = 8
