Question

The number of charter schools is 4 less than twice the number of alternative schools and there are 48 charter schools how many alternative schools are in the country

Answer 1

Let x = the number of alternative schools.

Therefore, 2x - 4 = 48.
                  2x -4 +4 = 48 + 4
                  2x = 52
                    x = 26

Therefore, there are 26 alternative schools(You could check this answer by substituting x=26 into the equation above.).
