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

I say step 4 is incorrect.

Salvador Hoffman · Answer 2

Equation 2 starts off at 4m=4+4n not - 4. so trace steps back to step 1 and look at the numbers again
