Question

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

Answer 1

given=X=2 and y=1

applying in the equation given,

2(2)+3(1)=k

k=7

Answer 2

$\huge\tt{Answer}$

Given:2x+3y=k

x=2

y=1

To find: value of k

Sol: 2x+3y=k

Putting the value of x=2 and y=1 in the given equation.

2(2)+3(1)=k

4+3=k

7=k
