#m=5#

Given that

#4m+9+5m-12=42#

#9m-3=42#

#9m=45#

#m=45/9#

#m=5#

#m=5#

We can combine our like terms on the left to get

#9m-3=42#

Remember, we want to isolate our #m# term. We can next do this by adding #3# to both sides. We get

#9m=45#

Dividing both sides by #9#, we get

#m=5#

Hope this helps!
