Question

if 2x +3y =10 and 3x + 2y = 15 find the value of (x + y)​

Answer 1

Answer:

ans. 5

Step-by-step explanation:

Answer 2

Answer:

=> x + y = 5

Step-by-step explanation:

Given equation:

$2x +3y =10$      $....(i)$

$3x + 2y = 15$      $....(ii)$

We have to find the value of x + y,

Add the equation ( i ) and ( ii ) we get,

=> 5x + 5y = 25

Now, taking 5 as common:

=> 5 ( x + y ) = 25

Divide 25 by 5, we get

$=> (x+ y)=\frac{25}{5}$

=> x + y = 5

Hence, the value of x + y is 5.
