Let x represent the number of days she practiced on weekdays.
She practiced 50 minutes on Saturday, so that accounts for 1 day.
On weekdays, she practiced for 30 minutes each day for a total of x days, which is 30x minutes.
If she practiced a total of 140 minutes for the week, the equation would be:
30x + 50 = 140
