Question

what are 2 numbers that subtract to 12 and divide to 4

Answer 1

Answer:

The two number which substrate to 12 and divide to 4  is 16 and 4.

Step-by-step explanation:

Let us consider the number be x and y.

Given that ,

            Two numbers that subtract to 12.

                   $x-y=12----(1)$

              Two number divide to 4.

                          $\frac{x}{y}=4\\ \\ x=4y\\ \\ y=\frac{x}{4} ----(2)$

Putting the value of y in equation (1),

              $x-y=12\\ \\ x-(\frac{x}{4})=12\\ \\ \frac{4x-x}{4}=12\\ \\ \frac{3x}{4} =12\\ \\ 3x=12 \cdot 4\\ \\ 3x=48\\ \\ x=\frac{48}{3} =16$

Putting the value of x in equation (1)

                 $y=\frac{x}{4}\\ \\ y=\frac{16}{4}=4$

The number are 16 and 4.
