Hi!
So we have to make a system of equations here.
Let sibling 1 be O and sibling 2 be Y (for older and younger)
So:
O + Y = 64
O = 64 - Y
(Either one works)
The older sibling is 6 years older.
O = Y + 6
Make everything in terms of Y.
64 - Y = Y + 6
Same to both:
58 = 2y
2y = 58
Divide by 2 on both sides:
y = 29
Since the older sibling is 6 years older:
29 + 6 = 35
Y = 29
O = 35
Let me know if you have any questions.

Step-by-step explanation:
LCD
you have 1 x not 2.
Suppose you have
y/3 + 3y/x + 7y / x
Unless there is something different about the question, you need only 1 x. The other one get's absorbed.
Answer: LCM = 3 * x
Answer:
D) 20
Step-by-step explanation:
Ml║ YK and YM║KL ⇒ YK= ML= 10
ML║KX and XL║KM ⇒ KX= ML=10
YX= YK + KX= 10+10= 20
YX= 20
