not a solution

#### Work Step by Step

3m+4 =19;6 To check whether 6 is the solution of the given expression, Substitute 6 for m 3*6+4 = 19 (multiply 3*6) 18 +4 = 19(add 18+4) 22$\ne$ 19 The statement is false because the values on both sides of the equation are different. Therefore, the number 6 is not the solution of the equation.
