You would solve this with simultaneous equations, so if we write it as:
5n + 2p = 9
3n + 2p = 6
(subtract)
2n = 3
÷ 2
notebooks = 1.5
Now you would substitute it in:
(3 × 1.5) + 2p = 6
4.5 + 2p = 6
- 4.5
2p = 1.5
÷ 2
pens = 0.75
So your final answer is notebooks are $1.50 and pens are $0.75, I hope this helps!

Answer:
<em>x<20/7</em>
Step-by-step explanation:
The expression is not well written. Fine the correct expression below
Given the expression 7x−9<11
Add 9 to both sides of the expression
7x-9+9<11+9
7x < 20
Divide both sides by 7
7x/7 = 20/7
x < 20/7
<em>Hence the required solution is x<20/7</em>
