Question

find the roots of a^3-181a+90​

Answer 1

Answer:

Step-by-step explanation:

Given:-

x = 2 and y = 1 is a Solution of the equation 2x + 3y = k.

To Find:-

The value of k .

Answer :-

If x = 2 and y = 1 is a solution of the linear equation then , on putting the values we get

⇒ 2x + 3y = k

⇒ 2x + 3y - k = 0

⇒ 2*2 + 3*1 - k = 0

⇒ 4 + 7 - k = 0

⇒ 11 - k = 0

Hence the value of k is 11.
