Step-by-step explanation:

- First, the data must be taken into account to create the equations:

- Where:

 X = Number of polio vaccines and Y = Number of measles vaccines.

Where for each polio vaccine there are 4 doses and for each measles vaccine there are 2 doses.

- We clear the variable that we want to find in each equation:

- Now both equations are equalized in terms of the same variable:

- Then X is cleared to find its value:

- Now we demonstrate the value of X obtained in equation 1 or 2 to give the values of Y

- Finally, both values are used to see if equation 2 gives us the correct data:

- The answer is given:

Dr. Potter gave 32 polio and 28 measles vaccines.
