This is linear......thus, either no solution, one solution or infinite solutions

 

2m+4(m-3) = 7m-4     simplify

 

2m + 4m - 12 = 7m - 4

 

6m - 12  = 7m - 4      add 12 to both sides, subtract 7m from both sides

 

-1m = 8         divide both sides by -1

 

m = - 8

 

 

 

cool cool cool

2m+4(m-3)=7m-4

 

\(2m+4m-12=7m-4\)  

 

-7m + 2m + 4m = -4 + 12

 

\(-m=8\)

 

\(m=-8\)   \(1 \ resultat\)
