Question

Two numbers have the sum of 761 and a difference of 335. Find the two numbers

Answer 1

The numbers are 548 and 213

Explanation:

Use a linear function:

Let x = 1st number

Let y = 2nd number

x+y=761

x-y=335

2x=1096

x=548

plug x into either equation

548+y=761

y=761-548

y=213

548-y=335

-y=-213

y=213
