Hi there! :)
Answer:
K=6.8
*The answer must have a decimal point.*
Step-by-step explanation:
First, you switch sides.
[tex]k+8.2=15[/tex]
Then, you subtract by 8.2 from both sides of an equation.
[tex]k+8.2-8.2=15-8.2[/tex]
Subtract by the numbers from left to right.
[tex]15-8.2=6.8[/tex]
Final answer is k=6.8
Hope this helps!
Thanks!
Have a nice day! :)
:D
