                                               6          4
solution

= m - 5 + m+1
     6         4

= 2(m – 5) + 3(m+1)
           12         

= 2m - 10 + 3m+3
           12         

= 2m + 3m + 3- 10
         12         

= 5m +  -7
      12         

= 5m - 7
     12         

=  5m - 7                 answer
