12 vans and 10 buses contain 304 students, 4 vans and 8 buses contain 204 students. How many students can a van carry?
\n" ); document.write( "Equations:
\n" ); document.write( "12v + 10b = 304 students
\n" ); document.write( "4v + 8b = 204 students
\n" ); document.write( "-----------------------------
\n" ); document.write( "Modify for elimination:
\n" ); document.write( "12v + 10b = 304
\n" ); document.write( "12v + 24b = 612
\n" ); document.write( "-----
\n" ); document.write( "Subtract and solve for \"b\":
\n" ); document.write( "14b = 308
\n" ); document.write( "b = 22 (# of students per bus)
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"v\":
\n" ); document.write( "4v + 8*22 = 204
\n" ); document.write( "4v + 176 = 204
\n" ); document.write( "4v = 28
\n" ); document.write( "v = 7 (# of students per van)
