Question

WHAT IS THE VALUE OF K ,IF (K,5) IS THE SOLUTION OF THE SIMULTANEOUS EQUATION 4X+3Y=19 AND 4X-3Y=-11​

Answer 1

Answer:

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.
