Answer 2

Answer:

x=2,y=1

Step-by-step explanation:

Given : $133x+87y=353$

            $87x+133y=307$

To Find:solve for x and y

Solution:

$133x+87y=353$ ---1

$87x+133y=307$  --2

Substitute the value of x from 1 in 2

$87(\frac{353-87y}{133}+133y=307$

$30711-7569y+17689y=40831$

$30711+10120y=40831$

$10120y=40831-30711$

$y=\frac{10120}{10120}$

$y=1$

Substitute the value of y in 1 to get value of x

$133x+87(1)=353$

$133x=353-87$

$x=\frac{353-87}{133}$

$x=1$

Hence the value if x is 2 and y is 1
