# Linear Algebra - Find the two numbers [closed]

The sum of two numbers is $$19,712$$.

One of the two numbers is divisible by $$10$$.

If the units digit of the number is erased, the other number is obtained.

What is the product of the two numbers?

$$10x+x = 19712.$$
$$11x = 19712.$$ $$x = 1792.$$
$$1792 + 17920 = 19712.$$
Ans: $$1792 \times 17920 = 32112640.$$
