8th grade math-solving equations with variables on each side?
My little sister needs help with her homework again.
For an annual fee of $30, you can join a movie club that will allow you to purchase tickets for $5.50 each at your local theater. If the theater charges $8 for movie tickets, write and solve an equation to determine how many movie tickets you will have to buy through the movie club for the cost to equal that of buying regularly priced tickets.

I'm positive the answer is 12, but I'm guessing on how I show the work.
Something like this: 8=30.00/x+5.50

I agree with Ronnie's Shoes the answer is 12 tickets. But make sure your sister knows how to do it.
$30+5.5(a variable)=8(the same variable)
then solve

first to do for you to assemble like words b, 2n+12=5n 12=5n-2n (substract the two factors by ability of 2n) 12=3n 12/3=3n/3 4=n a, 4(x-5)+2=x+3 (4x-20)+2=x+3 4x-18=x+3 4x-x=3+18 3x=21 x=7 divide the two factors by ability of three c, 4(y -2/4)=9(y+a million/3) 4y-2=9y+3 4y-9y=3+2 -5y=5 y=-a million divide the two factors by ability of -5
