Question:

____________

If X + Y=

14 and 2x + Y = 16 then find x

Answer:

__________

x = 2

y = 12

Explanation:

_______________

x + y = 14

2x + y = 16

Since, y is constant in both the equations , then -

2x + y = 16

- x + y = 14

x = 2

Hence, x = 2

Now,

2 + y = 14

=> y = 14 - 2

=> y = 12
