Ernesto tried to determine the solution for the system of equations using substitution. His work is shown below. x β y = 7 3x β 2y = 8 Step 1: x = y + 7 Step 2: 3(y + 7) β 2y = 8 Step 3: 3y + 7 β 2y = 8 Step 4: y + 7 = 8 Step 5: y = 1 Ernesto tried to determine the solution for the system of equations using substitution.
