What two numbers have a sum of 215 and a difference of 137

see below

Step-by-step explanation:

let x = big number

let you = small number

x + y = 215> (1)

x - y = 137 >(2)

(1)

x = 215 - y >(1)

substitute 1 into 2

215 - y -y = 137

-2 y = 78

y = 39

substitute y = 39 into (1)

x = 215 - (39)

x = 176

thus the numbers are 176 & 39
