What are the two numbers if the sum of two numbers is 82 and the difference is 36?

Answer 1

x = 59

y = 23

Let:

x = the first number

y = the second number

x + y = 82 -- equation (1)

x - y = 36 --- equation (2)

By Elimination:

x + y = 82

x - y = 36

=========

2x = 118 2x/2 = 118/2

x = 59

x + y = 82

y = 82 - x

y = 82 - 59

y = 23

check:

x - y = 39

59 - 23 = 36

36 = 36

Let x = 1st number

let y = 2nd number

X + Y = 82

X - Y = 36

add above equations

2X = 118

X = 59

Y = 23
