Question

the sum of 2 numbers is 52 and their is difference is 22 find the 2 numbers

Answer 1

Step-by-step explanation:

let the two numbers are=x,y

then x+y=52;x-y=22

in equation,

x+y=30+22

or,x+y=30+x-y

or,2y=30

or,y=15

Answer 2

Step-by-step explanation:

consider the two numbers as a and b so,

a+b = 52

a-b = 22

adding both equations we get,

2a = 74

so a = 37, substitute a in eq 1

37+b = 52

so b = 52-37 which is 15

therefore a = 37, b = 15
