21 - y = 12
-3.3 - 5y = -5
The steps for solving the given systeni of equations are shown below.
Step 1: -5(21 - y = 12)
-31 - 5y = -5
Step 2: โ101 + 5y = -60
-31 - 5y = -5
-13.5 = -65
Step 4:
= 5
Step 5:
2(5) - y = 12
Step 6:
Step 3:
y = -2
Solution: (5,-2)
Select the correct statement about step 3.
