answer to your question is-
let the first number be x qnd second number be y.
equation 1. x+y=25
equation 2.x-y=5
adding both equations
x+y=25
x-y=5
y is cancelled and the answer is 2x=30
x=30/2=15
now we will substitute value of x in equation 1
15+y=25
y=25-15
y=10
First number=15,Second number=10
