Question

Find the value of k, if x = 2, y = 1 is a solution of the equation 2x + 3y = k.​

Answer 1

Answer:

K=7

Step-by-step explanation:

if x = 2, y = 1

SUBSTITUTE IT IN THE EQUATION,

∴2*2 + 3*1=k

∴k=4+3=7

Answer 2

Step-by-step explanation:

Given: Linear equation 2x + 3y = k.

We can find the value of k by substituting the values of x and y in the given equation.

By substituting the values of x = 2 and y = 1 in the given equation

2x + 3y = k

⇒ 2(2) + 3(1) = k

⇒ 4 + 3 = k

⇒ Hence, k = 7

Therefore, the value of k is 7.
