Question

5x + y = 2 and 6x - 3y =1 by cross multiplication method

Answer 1

❤ CROSS - MULTIPLICATION METHOD ❤

➡ We know all the steps to apply cross multiplication method and thats what I had done.

➡ To solve this system of linear equation (cross-multiplication) system, we have to write the coefficients of the pair of linear equations.

➡ After that multiply the terms in the manner I have mentioned in the above picture.

➡ Proceed till you are getting the actual values of x and y.

➡ Whenever, you will get, you are all done.

✔✔✔ SO, I HOPE YOU UNDERSTANDS THIS METHOD ✔✔✔

$<b><i>Heya !$

Here's your answer !!

_______________________________

5x + y = 2

=> y = 2 - 5x

_____________________________

6x - 3y = 1

=> 6x = 1 + 3y

Substituting the value of y :

=> 6x = 1 + 3 ( 2 - 5x )

=> 6x = 1 + 6 - 15x

=> 6x + 15x = 7

=> 21x = 7

=> x = 7/21

=> x = 1/3

____________________________


=> x = 1/3 ANS


y = 2 - 5( 1/3 )

=> y = 2 - 5/3

=> y = ( 6 - 5 )/3

=> y = 1/3 ANS
