Question

The sum of two numbers is 188. The difference is 54. How do you find the numbers using a system of equations?

Answer 1

I found:
`x=121`
`y=67`

Explanation:

Call your numbers `x` and `y` so you get:
`{(x+y=188),(x-y=54):}` you can add the two equations (in columns) to get:
`2x+0=242`
`x=242/2=121` use this value into the first equation:
`121+y=188`
`y=188-121=67`
