9 - {-7}
Now distribute the negative once again.
9 + 7
And complete the indicated operation.

Answer:
b should be the answer
Step-by-step explanation:
First we want to find how much an individual biscuit costs.
If 5 biscuits costs 30p, then
5 x 1 biscuit = 30p
divide both sides by 5
1 biscuit = 6p
If one biscuit costs 6p, and we want to know how much 7 biscuits cost, then:
7 x 6p =42p
7 biscuits costs 42 p
The equation would be 21x+117=1000
