kitty is 4 years younger than mario three years from now she will be two thirds as older as mario .find their present ages
k = m-4
k+3 = 2/3 (m+3)
Now just solve for k and m.
To find the present ages of Kitty and Mario, we can set up a system of equations based on the information given.
Let's assume Kitty's present age is "k" and Mario's present age is "m".
According to the given information, Kitty is 4 years younger than Mario, so we can write the equation:
k = m - 4 ----(Equation 1)
Three years from now, both Kitty and Mario will be older. So, we can write the equation for Kitty:
k + 3 = (2/3)(m + 3) ----(Equation 2)
Now, we have two equations with two variables. We can solve this system of equations to find the values of "k" and "m".
Substituting Equation 1 into Equation 2, we get:
(m - 4) + 3 = (2/3)(m + 3)
Simplifying the equation:
m - 1 = (2/3)(m + 3)
To eliminate the fraction, we can multiply both sides of the equation by 3:
3(m - 1) = 2(m + 3)
Expanding and simplifying:
3m - 3 = 2m + 6
Bringing like terms to one side:
3m - 2m = 6 + 3
m = 9
Now, substitute the value of "m" back into Equation 1 to find "k":
k = m - 4 = 9 - 4 = 5
Therefore, Kitty's present age (k) is 5 years old and Mario's present age (m) is 9 years old.
