Question

2. Assertion : If x = 2, y = 1 is a solution of the equation 2x + 3y = k, then the value of k is 7. Reason: The solution of the line will satisfy the equation of the line.​

Answer 1

Solution :-

given that,

Assertion : If x = 2, y = 1 is a solution of the equation 2x + 3y = k, then the value of k is 7.

putting given values in given equation we get,

→ 2x + 3y = k

→ 2 * 2 + 3 * 1 = k

→ 4 + 3 = k

→ k = 7

So, Assertion is true.

Reason: The solution of the line will satisfy the equation of the line.
