Find k if (3,2) is solution of 5kx+2y=9​

Answer 1

Question

• Find k if (3,2) is solution of 5kx+2y=9

Solution

• Given that (3,2) is solution of 5kx+2y=9
• So from this we get to know as 3=x and 2= y.
• Now, substitute the values of x and y in the equation given.

⟼$\tt\bold{5kx + 2y = 9}$

⟼$\tt\bold{5k(3) + 2(2) = 9}$

⟼$\tt\bold{15k + 4 = 9}$

⟼$\tt\bold{15k = 9 - 4}$

⟼$\tt\bold{15k = 5}$

⟼$\tt\bold{k = \frac{15}{5} }$

⟼$k = \: \tt \cancel{ \frac{15}{5} }$

⟼$\tt\bold{k = \frac{1}{3} }$
