Question

find the value of k if (k,5) is the solution of the simultaneous equation 4x+3y=19 and 4x-3y=-11​

Answer 1

Answer:

k=1

Step-by-step explanation:

Here the solution of the eqn. is given is the form of graph coordinates. Therefore we need to interpret x=k and y=5.

Substituting the above values in any one of the equation, we get:-

4x+3y=19

=4(k)+3(5)=19

=4k+15=19

=4k=19-15

=4k=4

=k=1

We can verify the same by putting the values of x and y in the other given equation.
