10*1.61=1.79x+1.19(10-x)
\n" ); document.write( "16.1=1.79x+11.9-1.19x
\n" ); document.write( "16.1-11.9=1.79x-1.19x
\n" ); document.write( "4.2=.6x
\n" ); document.write( ".6x=4.2
\n" ); document.write( "x=4.2/.6
\n" ); document.write( "x=7 quarts of 1.79 cranberry juice
\n" ); document.write( "10-7=3 quarts of apple juice
\n" ); document.write( "proof
\n" ); document.write( "10*1.61=1.79*7+1.19*3
\n" ); document.write( "16.1=12.53+3.57
\n" ); document.write( "16.1=16.1
