how many solutions

2 solutions

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

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

$2m+4m-12=7m-4$  

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

$-m=8$

$m=-8$   $1 \ resultat$
