Question

Two numbers are in the ratio of 3:4. If they sum of the numbers is 63, find the numbers

Answer 1

27 and 36

Explanation:

Let's call the two numbers x and y.

`3x=4y \\\\x+y=63`

If you subtract y from both sides of the second equation, you can isolate x and substitute it into the first equation:

`x=63-y \\\\3(63-y)=4y\\\\189-3y=4y\\\\189=7y\\\\y=27\\\\x=63-27=36`

Hope this helps!
