1. Let's call the number of carter school: "x" and "y" the number of alternative school. Then, you have that:
- T<span>he number of charter schools is 4 less than twice the number of alternative schools. </span> - T<span>here are 48 charter schools in the country.
2. So, you have:
x=2y-4 (i)
x=48 (ii)
3. Then, when you substitute x=48 into the equation (i), you obtain: </span> x=2y-4 <span> 48=2y-4
4. Now, you must clear "y, as below:
48+4=2y 2y=52 y=52/2 y=26 </span><span> How many alternative schools are in the county? </span><span> The answer is: There are 26 alternative schools.</span>
