2m+4(m-3)=7m-4
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
\(2m+4m-12=7m-4\)
-7m + 2m + 4m = -4 + 12
\(-m=8\)
\(m=-8\) \(1 \ resultat\)
