Question

A+b=3
a-b=1
then what is the value of a and b

Answer 1

Answer :

a = 2 , b = 1

Solution :

Given equations :

a + b = 3 -------(1)

a - b = 1 --------(2)

Now ,

Adding eq-(1) and (2) , we get ;

=> a + b + a - b = 3 + 1

=> 2a = 4

=> a = 4/2

=> a = 2

Now ,

Putting a = 2 in eq-(1) , we get ;

=> a + b = 3

=> 2 + b = 3

=> b = 3 - 2

=> b = 1

Hence ,

a = 2 , b = 1

Answer 2

Answer:

a= 2

b=1
