m=m <---means there are infinte solutions m=x <---No solution x=1 <---one solution

Subtract 3n from both sides. $\huge~\rm~3n−7−3n=3n−6−3n$−7=−6 Add 7 to both sides. $\huge~\rm−7+7=−6+7$ $\huge~0=1$ so we have m=x case

a number that doesnt equal the same number means that there is no solution 0=1 would be no solution
