Question

solve the following linear pair of equation:- x+y=5 , x-y=13​

Answer 1

x+y = 5

x-y = 13

→ x+y+x-y = 5+13 → 2x = 18 → x = 9

Now, x+y = 5 → 9+y = 5 → y = 5-9 = -4

Answer 2

Answer:

$x = 9 \\ y = - 4$

Step-by-step explanation:

Given :

$x + y = 5 \\ x - y = 13$

Compare Above Equations and Add Both of Them ;

$x + y = 5 \\ x - y = 13 \\ - - - - - \\ 2x = 18 \\ x = \frac{18}{2} \\ x = 9$

Now Put x = 9 in Equation 1,

$x + y = 5 \\ 9 + y = 5 \\ y = 5 - 9 \\ y = - 4$
