Question

solve for x and y using eliminate method

2x-3y=10;4x-6y=20​

Answer 1

$\huge\underbrace\mathcal\pink{here \: is \: your \: answer}$

Given:

2x-3y = 10

=> 2x - 3y - 10 = 0 ----------- (i)

⠀⠀⠀

⠀⠀⠀⠀⠀⠀⠀

4x-6y = 20

=> 4x - 6y - 20 = 0

=> 2(2x - 3y - 10) = 0

=> 2x - 3y - 10 = 0 ----------(ii)

From equation (i) and (ii),

a1/a2 = b1/b2 = c1/c2

This means there are infinite number of solutions possible.

Hope you understand✌✌✌

Answer 2

Answer:

it is given that-

2x-3y=10.........(1)

4x-6y=20........(2)

We can write (1) eq. as-

x=10+3y

...........

2

substituting this value in (2) eq.

4(10+3y/2)-6y=20

20+6y-6y=20

20=20

because by substituting value the both part are equal so the equation has infinite solutions.
