Step-by-step explanation:

Let the number of hours used for softball practice be x.

Since soccer practice is 1.5 more hours more than 3 times as long as the softball practice. This will be:

= (3 × x) + 1.5 = 3x + 1.5

Therefore, we add both and equate to 15.

x + 3x + 1.5 = 15

4x + 1.5 = 15

4x = 15 - 1.5

4x = 13.5

x = 13.5/4

x = 3.375

Softball is practiced for 3.375 hours
