Question

find the value of k if (3,4) is a solution of the equation 3x-y=k​

Answer 1

Answer:

Value of K=5

That is

here ,given (3,4) is a solution of the given Equation

that is

x=3,y=4

there

substituting the values accordingly

3×3-4=k

9-4=k

5=k

k=5

Let's check whether it's correct or not

3×3-4=5

9-4=5

5=5

L.H.S=R.H.S

hence verified
