Question

Find the value of X Nd u , by elimination method 3x-y=3 ,9x-3y=9

Answer 1

Given equations

$3x-3y=3--(1)$

$9x-3y=9--(2)$

Multiplying the first equation by 3, we get,

$9x-9y=9--(3)$

Solving (2) and (3), we get,

$9x-9y=9\\\underline{9x-3y=9}\\\underline{\underline{-6y=0}}\\\implies y = 0$

Substituting y = 0 in the first equation, we get,

$3x-3(0)=3$

$\implies 3x=3$

$\implies x = 1$

$\boxed{\boxed{\bold{Therefore, \ the \ values \ of \ x \ and \ y \ are \ 1 \ and \ 0 \ respectively}}}}}}}}}}}}}$

                                                                   

Answer 2

Answer:

x=1 and y=0
