If and then find the value of (x + y).

Answer :

We have the given pair of equations are:



Now, multiplying (i) by 12 and (ii) by 4 we get:

3x + 4y = 5 …(iii)

2x + 4y = 4 …(iv)

Now, subtracting (iv) from (iii) we get:

x = 1

Now, putting the value of x in (iv) we get:

2 + 4y = 4

4y = 2



Hence, the value of (x + y) is
