Thanks
What have you tried?

Try expanding the LHS first:

So we have

Now put all the k's one one side and all the constants on the other.
3. Thanks
Would it be like this 7-21 = 3 - 5
-14=-2
(Sorry I'm really bad at maths.)

Um, first expand the brackets

7k-21= 3k-5

Then collect the like terms together

7k-3k=-5+21

Then simplify
4k=16
k=16/4
k=4

hope it helps
