Christin's age is equal to three times her age in 3 years' time minus three times her age 3 years ago. What is her age now?
Please explain how you got the answer as well, thanks.
ohyeah.
This question is pretty hard. Thank you for answering my question as well. I still don't understand it but thanks for your help lots, Damon! I appreciate it lots. Have a nice day!
c = 3(c+3) -3(c-3)
c = 3 c + 9 - 3 c + 9
c = 18
its 18 cause x*(x-3)-x+(x+3)
To find Christin's current age, let's break down the information given step by step:
1. Let's denote Christin's current age as C.
2. Her age in 3 years' time will be C + 3.
3. Her age 3 years ago would have been C - 3.
4. The given information states that her age in 3 years' time (C + 3) is three times her age 3 years ago (3 * (C - 3)).
So, we can write the equation: C + 3 = 3 * (C - 3).
Now, let's solve the equation:
Distribute the 3 on the right side of the equation: C + 3 = 3C - 9.
Combine like terms: C - 3C = -9 - 3.
Simplify: -2C = -12.
Divide by -2 to solve for C: C = (-12) / (-2).
The negatives cancel out, so C = 6.
Therefore, Christin's age now is 6.
Explanation: By setting up and solving the equation based on the given information, we were able to find Christin's current age.
