Verified Answer :

you answer is K= 7.8

Hi there! :)

Answer:

K=6.8

The answer must have a decimal point.

Step-by-step explanation:

First, you switch sides.

\(k+8.2=15\)

Then, you subtract by 8.2 from both sides of an equation.

\(k+8.2-8.2=15-8.2\)

Subtract by the numbers from left to right.

\(15-8.2=6.8\)

Final answer is k=6.8

Hope this helps!

Thanks!

Have a nice day! :)
