Let \"+x+\" gallons = a full tank
\n" ); document.write( "\"+%283%2F8%29%2Ax+%2B+6+=+%283%2F4%29%2Ax+\"
\n" ); document.write( "Multiply both sides by \"+8+\"
\n" ); document.write( "\"+3x+%2B+48+=+6x+\"
\n" ); document.write( "\"+3x+=+48+\"
\n" ); document.write( "\"+x+=+16+\"
\n" ); document.write( "The tank holds 16 gallons
\n" ); document.write( "check:
\n" ); document.write( "3/8 full is \"+%283%2F8%29%2A16+=+6+\" gallons
\n" ); document.write( "then, he buys 6 gallons
\n" ); document.write( "\"+6+%2B+6+=+12+\"
\n" ); document.write( "and 12 is 3/4 of a full tank
\n" ); document.write( "\"+%283%2F4%29%2A16+=+12+\"
\n" ); document.write( "\"+12+=+12+\"
\n" ); document.write( "OK\r
