Question

find 2x-3y=13 , x-4y=1​

Answer 1

Answer:

Step-by-step explanation:

 $2x-3y=13...(1)\\\\x-4y=1\\\\=>x=4y+1...(2)\\\\sub. this*eq*in*eq(1),we*get,\\\\=>2(4y+1)-3y=13\\\\=>8y+2-3y=13\\\\=>5y=11\\\\=>y=\frac{11}{5}$

sub. this in eq(2),we get,

  $x=4(\frac{11}{5} )+1\\\\=>x=\frac{44}{5}+1\\\\ =>x=\frac{(44+5)}{5}\\\\ =>x=\frac{49}{5}$

>>>Hope helps you<<<

Answer 2

Answer:

2x-3y=13............................1

x-4y=1  .........multiply this equation with 2

2x-8y=2..................................2

sub. equation 1 from 2

   2x-8y=2

   2x-3y=13

  -     +     -                sign are changed when subtracted

        -5y=-11

        5y=11

        y=$\frac{11}{5}$ ............Ans

    x-$\frac{11}{5}$*4=1

    x= $\frac{49}{5}$.............Ans
