Question

if (-5, k) lies on linear equation 3 X + 5 Y = 12 then find k

Answer 1

$\bold{\boxed{HEY!!!}}$

Here is your answer :-

We know that
every point on the line satisfies the equation.

Since ( - 5 , k ) lies on linear equation 3x + 5y = 12 , " x = - 5 and y = k "

Putting values of x & y in given equation

3 ( - 5 ) + 5k = 12

- 15 + 5k = 12

5k = 27

k = 27/5

k = 5.4

$\bold{\boxed{k = 5.4 }}$

Answer 2

( -5 , k )



Here,


X = -5 and Y = K





3X + 5Y = 12 -----------(1)



Putting X = -5 and Y = K in (1) , we get



3 × -5 + 5 × K = 12




-15 + 5K = 12




5K = 12 + 15




5K = 27



K = 27/5.
