Question

If x= 5 and y=3 is the solution of the equation equation 3x+ky=3

Answer 1

x=5
y=3

3x+ky=3
3*5+k*3=3
15+k*3=3
k*3=3-15
k*3=-12
k= -12/3
k= -4

Answer 2

Hola

Here is your answer ^_^


We have to find the value of k.

so, substitute the values x = 5 and y = 3

3(5) +k(3) = 3

15 + 3k = 3

3k = 3 - 15

3k = -12

therefore,

k = -12/3 => -4


Hence, k = -4

hope it helps !
