Given : Sum of two numbers = 140
Difference = 80
To Find : Numbers
Solution:
Let say numbers are a and b
a + b = 140 Eq1
a - b = 80 Eq2
Adding both equations
a + b + a - b = 140 + 80
=> 2a = 220
=> a = 110
Substitute in Eq1
=> 110 + b = 140
=> b = 140 - 110
=> b = 30
Hence two numbers are 110 and 30
