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.
