Question

2x - y = 6

X + 2y = 3. समीकरण में एक्स व वाई का मान होगा।​

Answer 1

AnsWer :

x = 3. and y = 0

Solution :

We have, Pair of Linear Equation.

$\tt \dagger \: \: \: \: \: 2x - y = 6. \: \: \: \: \: - (1)$

$\tt \dagger \: \: \: \: \: x + 2y = 3. \: \: \: \: \: - (2)$

Let try to find x and y by substitute method.

★ Taking Equation, ( 2 )

$\tt : \implies x + 2y = 3.$

$\tt : \implies x = 3 - 2y. \: \: \: \: \: - (3)$

Putting the value of x in Equation ( 1 ), We get.

$\tt : \implies 2x - y = 6.$

$\tt : \implies 2(3 - 2y) - y = 6.$

$\tt : \implies 6 - 4y- y = 6.$

$\tt : \implies 5y = 0.$

$\tt : \implies y = 0.$

Now, Putting the value of y in Equation ( 3 )

$\tt : \implies x = 3- 2y.$

$\tt : \implies x = 3- 2(0).$

$\tt : \implies x = 3.$

Therefore, the required answer is x = 3 and y = 0.
