Question

2x+ y=5; 2x-y=3 by elimination method​

Answer 1

Answer:

(2,1)

Step-by-step explanation:

WHEN WE ADD THE FIRST AND SECOND EQUATION "y" will get cancelled...

So the equation will become as

$4x = 8 \\ x = \frac{8}{4} \\ x = 2$

IF WE APPLY IT IN THE EQUATION WE WILL GET AS

$2(2) + y = 5 \\ 4 + y = 5 \\ y = 5 - 4 \\ y = 1$

Answer 2

Step-by-step explanation:

2x+ y=5; i

2x-y=3 ii

On adding both equations, we get

4x = 8

x = 2

on putting x =2 in equation i , we get

2(2) + y = 5

y = 1
