Answer:
7. x = 6
8. x = 2
Step-by-step explanation:
Rachel had 'x' chocolates initially. Claire gave her 3 more chocolates which made the total chocolates 9. How many chocolates did Rachel have initially?
[tex]$ x + 3 = 9 $[/tex]
[tex]$ \implies x = 6 $[/tex]
On a similar note, we have:
[tex]$ 4 + x = 6 $[/tex]
[tex]$ \implies x = 6 - 4 $[/tex]
[tex]$ \implies x = 2 $[/tex]
Hence the answer.
