For what number A does the equation 3Ax - 24 = 5x - 9 + x have no solutions for x?

3Ax - 24 = 5x - 9 + x        simplify the right side

 

3Ax - 24  =  6x - 9

 

This will have no solution when    3A  = 6  ⇒   A   = 2

 

To see why this is so....

 

3(2)x   - 24   =   6x - 24    and this can never equal  6x - 9
