Question

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

Equation 1: m = 8 + 2n
Equation 2: 6m = 4 + 4n





Step 1:

−6(m) =

−6(8 + 2n)

[Equation 1 is multiplied by −6.]





6m =

4 + 4n

[Equation 2]







Step 2:

−6m =

−48 − 12n

[Equation 1 in Step 1 is simplified.]





6m =

4 + 4n

[Equation 2]







Step 3:

−6m + 6m =

−48 − 12n + 4n

[Equations in Step 2 are added.]







Step 4:

0 =

−48 − 8n









Step 5:

n =

−6
