Question

11 → the linear equation 3x - 11y has

12 → find the value of k, if x = 1 , y = 2 is a solution of the equation 2x + 3y = k ​

Answer 1

Answer:

12- option A 7

Step-by-step explanation:

x=2. y=1

2x+3y=k

2(2) + 3(1)

4+3=k

7=k

Answer 2

Answer:

11:The linear equation 3x-11y=10 has: Unique solution. Two solutions. Infinitely many solutions.

12:We have been given the equation \[2x+3y=k\] and x=2, y=1, is a solution of the equation. Hence, the value of k is equal to 7.
