Question

the sum of 2 numbers is 137 and their difference be 43 find number

Answer 1

Let the numbers be a and b

According to question,

a + b = 137 ----------(1)

a - b = 43 -----------(2)

On adding equation 1 and 2, we get

2a = 180

=> a = 90

b = 137 - 90 =47

First number = 90

Second number = 47

Answer 2

let the two numbers be 'x' and 'y'

x + y = 137

x - y = 43

adding both equations we get,

2x = 180

x = 90

y = 47

Therefore the two numbers are 90 and 47.

hope this helps you
