Answer 3

Calculating the Number of Problems Solved by Masha

To calculate the number of problems Masha solved, we can use the information provided. Let's denote the number of problems Julia solved as J and the number of problems Masha solved as M. We are given that Julia and Masha together solved 22 problems, and Julia solved 4 more problems than Masha.

We can represent this information with the following equation: J + M = 22 (Equation 1) and J = M + 4 (Equation 2)

By substituting Equation 2 into Equation 1, we can solve for Masha's number of solved problems.

M + M + 4 = 22 2M + 4 = 22 2M = 22 - 4 2M = 18 M = 18 / 2 M = 9

So, Masha solved 9 problems.

Therefore, Masha solved 9 problems.
