Question

15x+17y=21 and 17x+15y=11 so x+y= ?​

Answer 1

Answer:

The value of x+y is 1.

Step-by-step explanation:

Here in the question, we have been given two equations and it has been asked to find the value of x+y.

For doing so we will solve it by using the elimination method as shown below:

⇒15x+17y=21

⇒17x+15y=11

⇒32x+32y=32

By taking 32 as common we will find the value of x+y as follows:

⇒x+y=1

Therefore the value of x+y from the given equations is 1.
