Penjelasan dengan langkah-langkah:

Let's call the smaller number "x" and the greater number "y".

From the problem statement, we know that:

x + y = 133 (equation 1)

4x = 3y (equation 2)

We can use equation 1 to solve for one of the variables in terms of the other. For example, we can solve for y in terms of x:

y = 133 - x

We can then substitute this expression for y into equation 2 and solve for x:

4x = 3(133 - x)

4x = 399 - 3x

7x = 399

x = 57

Now that we know x, we can use equation 1 to solve for y:

x + y = 133

57 + y = 133

y = 76

Therefore, the two numbers are 57 and 76.
