Question

if 3x -5y=14 2x-7y=2 then y ,x=

​

Answer 1

$\huge\underline\mathfrak\blue{Solution-}$

By using elimination method :

( 3x-5y=14 )×2

( 2x-7y=2 ) ×3

=> 6x-10y=28

6x-21y=6.......(1)

- + -

_________________

11y = 22

$\huge\boxed{y\:=\:2}$

_________________________________

Put y = 2 in eq 1

6x - 21(2) = 6

=> 6x - 42 = 6

=> 6x = 6+42

=> 6x = 48

=> x = 48/6

$\huge\boxed{x\:=\:8}$
