what is the sum of 2 numbers there sum is 35 and their difference is 15

Question

please no letters just answer

Answer 1

The easiest way to solve this question is with a system of equations using variables. Sorry, but looks like we need letters:

X + Y = 35

X - Y = 15

Add the 2 equations together:

2X = 50

X = 25

Plug that X back into either equation:

25 + Y = 35

Y = 10

So, the two numbers you are looking for are 25 and 10.
