Question

If(1,0) is a solution of the equation 8x+5k=18,then k=_____

Answer 1

The value of k is 2.

Step-by-step explanation:

The given equation is

$8x+5k=18$

Since, (1,0) is a solution of the equation then it must satisfy the equation as well.

Plugging x = 1 in the equation

$8\cdot1+5k=18$

Solve the equation for k

$8+5k=18\\\\5k=18-8\\\\5k=10\\\\k=2$

Therefore, the value of k is 2.

Answer 2

Answer:

k = 2

Step-by-step explanation:

The given equation is

8x+5k=188x+5k=18

Since, (1,0) is a solution of the equation then it must satisfy the equation as well.

Plugging x = 1 in the equation

8\cdot1+5k=188⋅1+5k=18

Solve the equation for k

\begin{lgathered}8+5k=18\\\\5k=18-8\\\\5k=10\\\\k=2\end{lgathered}

8+5k=18

5k=18−8

5k=10

k=2
