Let's represent notebook as "N"
And pencil as "P"
N + P = 4.50
N + P = 4.50
N = 2P
Given N is equal to twice P, we can substitute that directly into the first equation:
(2P) + P = 4.50
3P = 4.50
P = 1.50
Now that we have P, we can in turn
substitute that into either equation.
N + (1.50) = 4.50
N = 3.00
