$\bf 5x-\cfrac{y}{3}=13\quad \boxed{(\stackrel{x}{2}~,~\stackrel{y}{-9})}\implies 5(2)-\cfrac{-9}{3}=13\implies 10+3 = 13~ \checkmark

5x-\cfrac{y}{3}=13\qquad \boxed{(\stackrel{x}{3}~,~\stackrel{y}{-6})}\implies 5(3)-\cfrac{-6}{3}=13\implies 15+2\ne 13$

Answer:

Number of student = 25

Step-by-step explanation:

Let x be the number of student and y be the others

A new streaming service charges 5 dollars per month for students, and 10 dollars per month for everyone else

$x+y=55\\y=55-x$

$5x+10y=425$

replace y with 55-x

$5x+10y=425\\5x+10(55-x)=425\\5x+550-10x=425\\-5x+550= 425$

Subtract 550 from both sides

$-5x+550= 425\\-5x= -125\\x=25$

$y=55-x\\y=55-25\\y=30\\$

Number of student = 25
