#n=6#

Explanation:

#"distribute the bracket and simplify"#

#-12-30+10m=18#

#-42+10m=18#

#"add 42 to both sides"#

#10m=18+42=60#

#"divide both sides by 10"#

#m=60/10=6#

#color(blue)"As a check"#

Substitute this value into the left side of the equation and if equal to the right side then it is the solution.

#-12-5(-6)=-12+30=18#

#m=6" is the solution"#
