Answer:

I don't know sorry, I wish I could help you

hello!

Let's combine like terms:-

[tex]\bigstar{\sf{-4k+15k-30=-78}[/tex]

Add the k's:-

[tex]\bigstar{\sf{11k-30=-78}[/tex]

Add 30 to both sides:-

[tex]\bigstar{\sf{11k=-78+30}[/tex]

[tex]\bigstar{\sf{11k=-48}[/tex]

Divide both sides by 11:-

[tex]\bigstar{\boxed{\sf{k=4.36}}[/tex]

note:-
