Let $\"+x+\"$ = the number of gallons
\n" ); document.write( "to fill the tank
\n" ); document.write( "The car starts with
\n" ); document.write( " $\"+%281%2F3%29%2Ax+%2B+10+=+%283%2F4%29%2Ax+\"$
\n" ); document.write( "Multiply both sides by $\"+12+\"$
\n" ); document.write( " $\"+4x+%2B+120+=+9x+\"$
\n" ); document.write( " $\"+5x+=+120+\"$
\n" ); document.write( " $\"+x+=+24+\"$
\n" ); document.write( "-----------
\n" ); document.write( "The tank is 3/4 full, so 1/4 of a tank will fill it
\n" ); document.write( " $\"+%281%2F4%29%2A24+=+6+\"$
\n" ); document.write( "6 more gallons will fill the tank
