Question

find the value of K, if ( -2 , -3 ) is solution of equation 2x - 5y -2k=0​

Answer 1

Step-by-step explanation:

Given:-

• (x, y) = ( -2 , -3)

Solution:-

Put x= -2 and y = -3 in the given equation

• 2x - 5y - 2k = 0
• 2(-2) - 5(-3) - 2k = 0
• -4 + 15 - 2k = 0
• 11 - 2k = 0
• -2k = -11
• k = -11/-2
• $k \: = \frac{11}{2}$

Answer 2

Answer:

k = 5.5 or 11/2

Step-by-step explanation:

(-2,-3) is the solution so

the value of x=-2 and y=-3

then for finding the value of k

let's substitute value of x and y in equation

2(-2) - 5(-3) - 2k =0

- 4 + 15 - 2k = 0

11 - 2k = 0

then sifting 11 to RHS

- 2k = 0 - 11

- 2k = -11

then after cancelling same sign on both the side

we get

2k = 11

then

k = 11/2

•°•k = 5.5 or 11/2
