_____x+_____=_____
25,45,120

Answer 1

Let's let x represent the number of weekdays Johan practiced.
On Saturday, he practiced 45 minutes.
On the weekdays, he practiced 25 minutes each day, so he practiced for 25x minutes on the weekdays.
So the total amount of practice time is 45 + 25x minutes.
The equation in the form of px + q = r is:
25x + 45 = 120
