How do I figure this step by step please...m+3n=7; n= 0,1,-2

Question

Solve for m. Thrn take value of m for each value of n

Answer 1

m + 3n = 7

 

Subtract 3n from both sides:

 

m = 7 - 3n

 

For n = 0, m = 7 - 3(0) = 7

 

For n = 1, m = 7 - 3(1) = 4

 

For n = -2, m= 7 - 3(-2) = 13

Answer 2

m + 3n = 7 for n = 0, 1, -2

 

First set it to: m = 7 - 3n

 

If you substitute 0, then 1, then -2, you will get: m(0) = 7 - 0, m(1) = 7 - 3, m(-2) = 7 + 6 respectively

 

This gives us: m(0) = 7, m(1) = 4, m(-2) = 13
