Answer 1

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

Answer 2

hello!

Let's combine like terms:-

`\bigstar{\sf{-4k+15k-30=-78}`

Add the k's:-

`\bigstar{\sf{11k-30=-78}`

Add 30 to both sides:-

`\bigstar{\sf{11k=-78+30}`

`\bigstar{\sf{11k=-48}`

Divide both sides by 11:-

`\bigstar{\boxed{\sf{k=4.36}}`

note:-
