    so you work backwards. you take 46 and add 10 because it says "10 less than"

    you get 56 .now since it says "twice the number" you do the opposite and divide 56 by 2. and voila

    Let c = the number of charter schools. Let a = the number of alternative schools. c = 2*a - 10. Number of charter schools is 46. This makes our equation equal to: 46 = 2*a - 10 Add 10 to both sides of this equation to get: 56 = 2*a Divide both sides of this equation by 2 to get: a = 28 There are 28 alternative schools in the country.
