#LHS = RHS" "rarr m= 11# is the correct solution

You could solve the equation for yourself and see if the solution comes out as 11.

Or, substitute the value #11# for every #m#.

If you end up with a TRUE statement, then #11# is the solution.

If the statement is FALSE, then #m# is not the solution.

#LHS: 9m-7m-5" "RHS: 17#

#=9(11)-7(11)-5#

#=99-77-5#

# = 17#.

#LHS = RHS" "rarr m= 11# is the correct solution
