\huge\bf{ANSWER:}


\huge\mathrm{k=6}\checkmark


\huge\bf{SOLUTION:}

Hey there, hope you are enjoying your day! :)

Let's solve this math problem. First of all, let's use the Distributive Property:


\rm{5+4(k-1)=25


\rm{5+4k-4=25

Now, move all the constants (numbers without a variable next to them) to the right, using the opposite operation:


\rm{4k=25-5+4


\rm{4k=20+4

Add:


\rm{4k=24

Divide both sides by 4 in order to isolate k:


\rm{k=6} (Answer)

Hope you find it helpful.

Feel free to ask if you have any doubts.

Answer:

k=6

Explanation:

subtract 5 from both sides

4(k-1)=20

divide 4 on from both sides

k-1=5

add 1 on both sides

k=6
