Question

11x+6y=4330 ; 22x-6y=5240
find x+y​

Answer 1

Answer:

X= 290

Y= 190

Step-by-step explanation:

add both the terms and you will get value of x.

later substitute value x in any equation and you will get the answer

Answer 2

The value of x+y is 480.

Given: Given equations are 11x+6y=4330; 22x-6y=5240.

To find: We have to find x+y.

Solution:

The given equations are 11x+6y=4330 and 22x-6y=5240.

11x+6y=4330---------(1)

22x-6y=5240-------(2)

Adding equations (1) and (2) we get-

$11x+6y + 22x-6y=5240 + 4330 \\ 33x = 9570 \\ x = 290$

Thus, the value of x is 290.

Putting the value of x in the equation (1) we get-

$11 \times 290 + 6y = 4330 \\ 3190 + 6y = 4330 \\ 6y = 1140 \\ y = 190$

Thus the value of y is 190.

So, the sum of x and y will be-

$290 + 190 \\ = 480$

The sum of x and y is 480.

Thus the value of x+y is 480.
