You can put this solution on YOUR website!
if r = 5z and 15z = 3y, then r = ?????
\n" ); document.write( "take 15z = 3y and solve for z.
\n" ); document.write( "you get:
\n" ); document.write( "z = 3y/15
\n" ); document.write( "not you take r = 5z and you substitute for z to get:
\n" ); document.write( "r = 5 * 3y/15 which becomes:
\n" ); document.write( "r = 15y/15 which becomes:
\n" ); document.write( "r = y\r
\n" ); document.write( "\n" ); document.write( "
\n" ); document.write( "
