Question 793472
{{{-7+9m=m-15}}} Start with the given equation.



{{{9m=m-15+7}}} Add {{{7}}} to both sides.



{{{9m-m=-15+7}}} Subtract {{{m}}} from both sides.



{{{8m=-15+7}}} Combine like terms on the left side.



{{{8m=-8}}} Combine like terms on the right side.



{{{m=(-8)/(8)}}} Divide both sides by {{{8}}} to isolate {{{m}}}.



{{{m=-1}}} Reduce.

Answer:


So the solution is {{{m=-1}}}
