Question

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

Answer 1

Answer:

K=1

Step-by-step explanation:

The given equation is 4x+3y=19

Solution is (k, 5) which is in the form of (x, y)

Then,

4(k)+3(5)=19

4k+15=19

4k=19-15

4k=4

K=4/4=1

Another equation is 4x-3y=-11

Then,

4(k)-3(5)=-11

4k-15=-11

4k=-11+15

4k=4

K=4/4=1
