Solve 7(k-3)=3k-5
First we need to multiply out the bracket
7k-21=3k-5
Then we must make sure our variable is only on one side so we need to deduct 3k from both sides
4k-21=-5
Now we should isolate our variable so add 21 to both sides of our equation
4k=16
Finally dividing by 4 gives us k alone
k=4
