Answer 1

Answer:

2

Step-by-step explanation:

x= 3,

y =2

3(3) - k(2) = 5

9 - 2k = 5

- 2k = -4

+2k = +4

k = 4/2

k = 2

Answer 2

Answer:

• Option (a) 2, is your answer

Explanation:-

As given in question:-

Let ,

x=3 and y=2

put this in eqn that is given in question

➜3x – ky = 5

➜3(3)-k(2)=5

➜9- 2k= 5

➜-2k=5-9

➜-2k=-4

[negative sign cancel each other]

➜2k=4

➜k=2

Hope it helps you!!
