Find the number of ordered pairs (m,n) which satisfy the system

 

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

3/2n = 4-2m

 

And if the answer is infinite type infinite. :)

4m-4n = 7- 7n                  3/2 n = 4-2m

4m + 3n = 7                      3n = 8-4m

                                          3n + 4m = 8

  

 

4m+3n = 7                         4m + 3n = 8        Hmmmmm looks like NO solutions !
