Question

x+y=19
x-y=15
find the value of x and y of both

Answer 1

Answer:

The Correct Answer is x = 17 and y = 2

Step-by-step explanation:

x+y=19 --- (1)

x-y=15 ---- (2)

On Adding both the equations we get,

2x + y - y = 34

2x = 34

x = 17

Now, putting x = 17 in equation (1)  

17 + y = 19

y = 2

Answer 2

As per data given in the question,

We have to determine the value of x and y.

From the given data,

It is given that,

$x+y=19 --- (1)\\x-y=15 --- (2)$

Now for solving the value of x and y we need to solve the given equation.

As here if we add both the equation then the co-efficient of y will become zero, and by solving the obtained expression, we can determine the value of x.

So,  Adding both the equations we will get,

$2x + y - y = 34\\=>2x = 34\\=>x = 17$

For finding the value of y we can get it by putting the value of x in any of above equation,

So, putting x = 17 in equation (1)  

We will get,

$17 + y = 19\\=>y = 2$

Hence, value of x and y after solving the above given expression will be x = 17 and y = 2.
