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?
Step 1
Step 2
Step 3
Step 4
