Question

4) What is the value of K, if (K, 5) is the solution of the simultaneous equations 4x + 3y = 19
& 4x – 3y = -1?
A) 4
B) -
C) 5
D) 1​

Answer 1

Answer:

Correct option is

D

1

Since, (k,5) is the solution of simultaneous equation.

Therefore, it should satisfy the given equations.

4(k)+3(5)=19

4k=4

k=1

Also,

4k−3(5)=−11

4k=4

k=1

Therefore, the value of k=1

Hence, this is the answer.
