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


Equation 1: m = 8 + 2n

Equation 2: 4m = 4 + 4n


Step 1: −4(m) = −4(8 + 2n) [Equation 1 is multiplied by −4.]

4m = 4 + 4n [Equation 2]

Step 2: −4m = −32 − 8n [Equation 1 in Step 1 is simplified.]

4m = 4 + 4n [Equation 2]

Step 3: −4m + 4m = −32 − 8n + 4n [Equations in Step 2 are added.]

Step 4: 0 = −32 − 4n

Step 5: n = −8



In which step did the student first make an error?
