Gym1: 50 dollars plus 4 dollars per session
$50 + 4x
Gym2 : 30 dollars plus 6 dollars per session
$ 30 + 6x
when do they cost the same
50+4x = 30 + 6x
subtract 4x rom each side
50 +4x -4x = 30 +6x-4x
50 = 30 -2x
subtract 30 from each side
50 -30 = 30 -30+2x
20 = 2x
divide by 2
20/2= 2x/2
10 =x
They cost will be equal when they have 10 sessions
