Answer:
is this by any chance about simultaneous equations? If so,
Step-by-step explanation:
Step 1 is telling us to decide on whether x and y should be the unknown. For instance, you want x to be the unknown, so u solve for x.
Step 2 is telling us to write equations with x and y.
For example,
7x + 5y = 12
7x - 2y = 9
This may not be accurate but it is an equation.
Step 4 is telling us to check whether the solution is accurate or not. For instance, we say 7 is x. so we substitude 7 into the original equation to see whether the answer we found is correct.
For step 5, im not really sure.
hope this helps though???

60£
Peter = 2 Angard
Angard = 3 Nick
Peter = 2 Angard = 6 Nick
Angard = 3 Nick
Nick = 1 Nick
6+3+1=10 Nick
60£/10 = 6£
Nick = 6£
Angvard = 3 Nick = 6£*(3) = 18£
Peter = 6 Nick = 6£*(6) = 36£
(prove: 6+18+36=60£)
The answer is C. Hope this helps
