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

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

Step 1: −2(m) = −2(6 + n)
2m = 8 + 8n

Step 2: −2m = −12 − 2n
2m = 8 + 8n

Step 3: −12 − 2n = 8 + 8n

Step 4: −20 = 10n

Step 5: n = −2

Question

The work of a student to solve a set of equations is shown below:

Equation 1: m = 6 + n
Equation 2: 2m = 8 + 8n


Step 1: 	−2(m) = 	−2(6 + n)
 	2m = 	8 + 8n
 
Step 2: 	−2m = 	−12 − 2n
 	2m = 	8 + 8n
 
Step 3: 	−12 − 2n = 	8 + 8n
 
Step 4: 	−20 = 	10n
 
Step 5: 	n = 	−2
