Question

Find two numbers, if Their sum is −7 and their difference is 14

Answer 1

let those numbers be x and y

According to your question

x + y = -7

x - y =14

adding both equations

2x = 7

or x = 7/2

substitute value of x in either equation

y = -21/2

So,

x= 7/2

y=-21/2

Hope this helps!
