24x+10*10=14(10+x)
\n" ); document.write( "24x+100=140+14x
\n" ); document.write( "24x-14x=140-100
\n" ); document.write( "10x=40
\n" ); document.write( "x=40/10
\n" ); document.write( "x=4 grams of 24 caret gold is needed.
\n" ); document.write( "Proof:
\n" ); document.write( "24*4+10*10=14(10+4)
\n" ); document.write( "96+100=14*14
\n" ); document.write( "196=196
