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

Explanation:

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
