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"#
