Question

The difference between two numbers is 378. When the smaller number is doubled, the result is 1488. What is the greater number ?​

Answer 1

Answer:

Let us write the given conditions as equations.

We get:

x-y=21 and

x/2 +2y=38

Solving the 2 equations for x and y we get x=32 and y=11

Indeed 32–11= 21 and 16+22=38
