Answer:
Associative property of addition
Step-by-step explanation:
X/x-3 + x/2 = 6x/2x-6
⇒ x/x-3 + x/2 = 3x/x-3
⇒ x/x-3 - 3x/x-3 = -x/2
⇒ -2x/x-3 = -x/2
Two cases:
1) x = 0
2) x ≠ 0
⇒ 2/x-3 = 1/2
⇒ x-3 = 4
⇒ x = 3+4 = 7
Solutions are: x= 0,7
Hope it helps!

Answer:
Kim is 16 years old and her sister is 8 years old.
Step-by-step explanation:
We can use equations to represent this scenario.
Let Kim's age be 'k' and her sister's age be 's'.
Thus, k=2s (since Kim's age is double of her sister)
and k+s=24 (their ages add to 24 (from question)
Substituting the first equation:
2s+s=24
3s=24
s=8
Therefore, Kim's sister is 8 years old.
Now substitute this value into the second equation:
k+8=24
k=16
Therefore, Kim is 16 years old.
