Answer:

Step-by-step explanation x + y = 47 {sum of two numbers is 47}

x - y = 15 {difference of two numbers is 15}

---------------

2x = 62 {added the two equations together}

x = 31 {divided both sides by 2}:
The sum of two numbers is 47 and the difference is 15. We could write an equation for this; x+15=47. x would be 32, so the two numbers would be 32 and 15, and would sum up to 47
