Question

if 5x+3y=8, 3x+5y=0 then find the value of x+y​

Answer 1

$\huge\mathfrak\blue{Answer:}$

$\huge\orange{x + y = 1}$

Step-by-step explanation:

Given:

$5x + 3y = 8 -----(1)$

$3x + 5y = 0 -----(2)$

To Find:

$x + y = ?$

Solution:

Adding Equations (1) and (2):

$>> 5x + 3x + 3y + 5y = 8 + 0$

$>> 8x + 8y = 8$

$>> 8 (x + y) = 1 \times 8$

On Cancelling off 8 from both sides of the Equation:

$\orange{>> x + y = 1}$
