The sum of 2 numbers is 35 and their difference is 15

x = 25,

y = 10

Step-by-step explanation:

Call the larger number "x", and the smaller one "y".

Set up a system, based on the given infomration

x + y = 35

x - y = 15

Solve the system by elimination, in this case, one can just add the two systems to eliminate a variable.

x + y = 35

x - y = 15

x + y + x - y = 15 + 35

Simplify,

2x = 50

Inverse operations,

2x = 50

/2     /2

x = 25

Substitute back in to find y,

x + y = 35

x = 25

25 + y = 35

Inverse operations,

25 + y = 35

-25         -25

y = 10
