y=3x
\n" ); document.write( "x+y=4500 solve this by elimination
\n" ); document.write( "----
\n" ); document.write( "Rearrange:
\n" ); document.write( "3x-y = 0
\n" ); document.write( "x +y = 4500
\n" ); document.write( "-----
\n" ); document.write( "Add ans solve for \"x\":
\n" ); document.write( "4x = 4500
\n" ); document.write( "x = 1125
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "y = 3x
\n" ); document.write( "y = 3*1125 = 3375
