Archie's gas tank is 1/3 full. If Archie adds 3 gallons of gas to the tank it will be 1/2 full.
\n" ); document.write( "what is the capacity in gallons of Archie's tank?
\n" ); document.write( ":
\n" ); document.write( "Let x = tank capacity
\n" ); document.write( ":
\n" ); document.write( "Write an equation for what it says:
\n" ); document.write( "\"1%2F3\"x + 3 = \"1%2F2\"x
\n" ); document.write( ":
\n" ); document.write( "Multiply each term by 6 to get rid of the denominators. results:
\n" ); document.write( "2x + 6(3) = 3x
\n" ); document.write( "18 = 3x - 2x
\n" ); document.write( "x = 18 gal tank
\n" ); document.write( "
\n" );
