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

Question

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
