Question

ii. What is the value of k, if (k,5) is the solution of 4x+3y=19 and 4x-3y=-11?
​

Answer 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
