Hi there! Hopefully this helps!

---------------------------------------------------------------------------------------------------

Answer:
\boxed{k = -7}

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


-30=5k+5

Swap sides so that all variable terms are on the left hand side.


5k+5=-30

Subtract 5 from both sides.


5k=-30-5

Subtract 5 from −30 to get −35.


5k=-35

Divide both sides by 5.


k=(-35)/(5)

Divide −35 by 5 to get, you guessed it, -7!

You can also do "5(-7) + 5 = ??" For proof.
