Question 424424
Solution: Denote the unknown number x, base on the given data write the equation:

         {{{(2/3)*x-10=(1/4)*x}}} Multiply both sides with LCD 12.

         {{{8*x-120=3*x}}}

           8x-3x=120

            5x=120 Divide both sides with 5

             x=24

Check: 2/3*24-10=1/4*24 => 16-10=6 => 6=6.

Answer: The unknown number is 24
