Question

A + b = 10
a - b = 2

Answer 1

a = 6 , b = 4

Explanation:

a + b = 10................equation 1

a - b = 2..................equation 2

Solving equation 1 and 2 we get

a + b = 10

a - b = 2

2a = 12

a = 12/2

Therefore a = 6

Now

putting a = 6 in equation 1

6 + b = 10

b = 10 - 6

Therefore b = 4
