Michael solved the system of linear equations and provided the solution.
3x – 3y = 6
4x – 7y = 2
Step 1 4(3x –3y = 6)
–3(4x – 7y = 2)
Step 2 12x – 12y = 24
–12x + 21y = –6
Step 3 –33y = 30
Step 4 y equals negative 10 over 11
In which step did Michael show his first error?
Step 2
Step 3
Step 4
No errors are present in the solution
