April wants to prove that she can solve the system of equations below 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?

• 7x + 2y = 2

• -x +2y = 2

• 3x + (4x-6) = 8

• 3(4x-6) +y = 8

Emily makes $10 per hour at her job.  Her paycheck was $370.  If h represented the number of hours Emily worked, which equation below represents Emily's paycheck?
