Question

if(3, 5 is a solution of the equation 2 X + 5 y is equal to k find the value of k​

Answer 1

Answer:

$\huge{\boxed{\rm{\pink{K=31}}}}$

Step-by-step explanation:

Given equation is 2x+5y=k

If the given point (3,5) is a solution then it satisfies the given equation .

Put x=3 and y=5 in the given equation then

=>2(3)+5(5)=k

=> 6+25=k

=>31=k

Therefore,K=31

Answer 2

$\huge\mathbb\blue{31}$

Given:

2x+5y=k

and value of x and y = 3,5 respectively

Solve:

$\large\red\implies\star{}$2x+5y=k

$\large\red\implies\star{}$2(3)+5(5)

$\large\red\implies\star{}$6+25=31

k=31
