2x - 8y + 5 = 0
___

Answer 1

Hi,

Here's ur answer:-

3x-4y-1 = 0

=> 3x-4y = 1

=> 6x-8y = 2---(¡)

2x-8y+5 = 0

=> 2x - 8y = -5

=> 6x -24y = -15----(¡¡)

Subtracting (¡¡) from (¡),

6x-8y = 2
6x -24y = -15
__________
24y-8y = 2+15

=> 16y = 17

=> y = 17/16

3x-4y = 1

=> 3x - 17/4 = 1

=> 3x = 17/4 +1 = 21/4

=> x = 7/4

So, x = 7/4, y = 17/16

HOPE IT HELPS (^_^)☺
