Ok, so the first thing you have to to do is assign a letter to each object, so the spoon can be "s" and the knives can be "k". Then you have to turn the word problem into a simultaneous equation (I presume that you know how to solve a simultaneous equation). So, since a simultaneous equation has two equations we need to group the information in the word problem into two separate equations. the first equation would be k=3s, since a knife is three times the cost of a spoon. The second equation is 9s+3k=£82.80. Now that you have the two equations you should be able to solve the rest.
Hope this helps!
BTW, what year are you in?

Ok, so it should look like this:
K=3s
9s+12k=82.80
12 x 3=36
9s+36s=45s
45s=82.80
Can you solve the rest now?
