A mother is 4 times as old as her daughter. In 4 years, the mother will be 3 times as old as her daughter. How many years old is the daughter now?

I came up with two equations:
M = 4D and M + 4 = 3(4 + D)

and I got D to be 12 but that isn't the correct answer??

M = 4D and M + 4 = 3(4 + D)

4 D + 4 = 12 + 3 D
1 D = 12 - 4
D = 8

so di ko alam pero AHAHAHAHA goodluck na lang di ko rin alam eh HAHAHAHA

TRANSLATION:
I also don't know the answer AHAHAHAHA But, I wish you goodluck and again, I also don't know.

Let's solve the problem step by step. We'll use algebraic equations to find the correct answer.

Let's assume the daughter's age is represented by the variable D and the mother's age is represented by the variable M.

According to the problem statement, the mother is 4 times as old as her daughter. So we can write the equation:

M = 4D -- Equation 1

Now, let's consider the second part of the problem. In 4 years, the mother will be 3 times as old as her daughter will be. This gives us another equation:

M + 4 = 3(4 + D) -- Equation 2

To solve these equations simultaneously, we can start by substituting Equation 1 into Equation 2:

4D + 4 = 3(4 + D)

Now, let's solve for D:

4D + 4 = 12 + 3D
4D - 3D = 12 - 4
D = 8

According to the calculation, the daughter is 8 years old. However, this seems to contradict your answer of 12. It's important to recheck your work and ensure that the equations and calculations are correct.
