x+3=3(x-3)
That is, I am 6 years old this year.
Monkey:
x+2=2(x-2)
That is, I am 4 years old this year.
The sheep is X and the monkey is Y.
X+3=3(X-3)
Y+2=2(X-2)
Find X=6 Y=6.
Suppose Sister A is old.
If A+3/A-3=3, A=6.
Similarly, suppose Monkey Brother B is old.
B+2/B-2=2，B=6。
Here are the answers: Sister Sheyang is now X years old, and Brother Sheyang is now Y years old, so:
3 (x-3) = x+33x-9 = x+32x-12 = 0, so X=6.
2(Y-2)=Y+2 2Y-4=Y+2 Y-6=0, so Y=6.
So Brother Monkey is as big as Sister Sheep, and both are 6 years old.
If you are satisfied with the following answer, don't forget to use the following answer as the best answer!
Solution: Suppose Sister Yang is X years old this year. Brother monkey is y years old this year.
X= 12, where x+3/x-3=3.
Y+2/y-2=2，y=6。
Answer: Sister Yang 12 years old, Brother Monkey is 6 years old.
Sister Sheyang is now X years old, and Brother Snake Monkey is now Y years old.
X+3=3X
X= 1.5 years old
Y+2=2Y
Y=2 years old
So Sister Yang is now 1.5 years old, and Brother Monkey is now 2 years old.
