The work of a student to solve a set of equations is shown below:

Equation 1: m=8+2n

Equation 2: 4m = 4+4n

Step 1: - 4 (m) = -4 (8+2n)

4m = 4 + 4n

Step 2: - 4m=-32-8n

4m = 4 + 4n

Step 3: - 4m+4m = - 32 - 8n + 4n

Step 4: 0 = - 32 - 4n

Step 5: n=-8

In which step did the student first make an error?
