5*.80+2.40x=1.40(5+x)
\n" ); document.write( "4+2.4x=7+1.4x
\n" ); document.write( "2.4x-1.4x=7-4
\n" ); document.write( "x=3 pounds of carmal is used.
\n" ); document.write( "Proof:
\n" ); document.write( "5*.80+2.40*3=1.40(5+3)
\n" ); document.write( "4+7.2=1.40*8
\n" ); document.write( "11.2=11.2
