Solve problem.
I think the answer is 10 cats
Jen has X cats.
Sister has 3x-2 cats.
3x-2 = 4
X =
3x-2 = 4

-2+2=4+2
3x=6
3x/3=6/3
x=2
Chloe has twice as many cats as her sister has dogs. Her brother has two turtles. Together, they have twelve pets. Write an equation that can be used to find how many of each pet they have.
To solve this problem, let's first define some variables. Let's say the number of cats Jen has is represented by the variable "J", and the number of cats her sister has is represented by the variable "S".
We're given two pieces of information:
1) Jen's sister has four cats, so S = 4.
2) Jen's sister has two less than three times as many cats as Jen, which can be written as S = 3J - 2.
Now, we have two equations:
S = 4
S = 3J - 2
We can substitute the value of S from the first equation into the second equation:
4 = 3J - 2
To solve for J, we can add 2 to both sides of the equation:
4 + 2 = 3J - 2 + 2
Simplifying, we get:
6 = 3J
Now, divide both sides of the equation by 3:
6/3 = 3J/3
2 = J
Therefore, Jen has 2 cats.
It seems like there was an error in your earlier calculation. The correct answer is 2 cats, not 10 cats.
