Let the number of students who listed basketball as their favorite sport be x .
Then number of students who listed soccer as their favorite sport = 3x - 17
Let us use the following equation to find the number of students who listed basketball as their favorite sport :-
[tex]x + 3x - 17 = 487[/tex]
[tex]4x - 17 = 487[/tex]
[tex]4x = 487 + 17[/tex]
[tex]4x = 504[/tex]
[tex]x = \frac{504}{4} [/tex]
[tex] x= 126[/tex]
Number of students who listed soccer as their favorite sport :-
[tex] = 3x - 17[/tex]
[tex] = 3 \times 126\: - 17[/tex]
[tex] = 378 - 17[/tex]
[tex] = 361[/tex]
361 students listed soccer as their favorite sport .
