You can put this solution on YOUR website!
Note that \"+1.2x+%2B+1.4y+\" is the total cost of
\n" ); document.write( "the o.j. and p.j. used.
\n" ); document.write( "So you need to divide this by total liters needed
\n" ); document.write( "to get the cost/liter
\n" ); document.write( "(1) \"+%28+1.2x+%2B+1.4y+%29+%2F+8+=+1.24+\"
\n" ); document.write( "and the other equation is:
\n" ); document.write( "(2) \"+x+%2B+y+=+8+\"
\n" ); document.write( "----------------
\n" ); document.write( "(1) \"+1.2x+%2B+1.4y+=+1.24%2A8+\"
\n" ); document.write( "(1) \"+1.2x+%2B+1.4y+=+9.92+\"
\n" ); document.write( "(1) \"+120x+%2B+140y+=+992+\"
\n" ); document.write( "Multiply both sides of (2) by \"+120+\"
\n" ); document.write( "and subtract (2) from (1)
\n" ); document.write( "(1) \"+120x+%2B+140y+=+992+\"
\n" ); document.write( "(2) \"+-120x+-+120y+=+-960+\"
\n" ); document.write( "\"+20y+=+32+\"
\n" ); document.write( "\"+y+=+1.6+\"
\n" ); document.write( "and, since
\n" ); document.write( "(2) \"+x+%2B+y+=+8+\"
\n" ); document.write( "(2) \"+x+%2B+1.6+=+8+\"
\n" ); document.write( "(2) \"+x+=+6.4+\"
\n" ); document.write( "6.4 liters of OJ and 1.6 liters of PJ are needed
\n" ); document.write( "-------------
\n" ); document.write( "check answer:
\n" ); document.write( "(1) \"+%28+1.2x+%2B+1.4y+%29+%2F+8+=+1.24+\"
\n" ); document.write( "(1) \"+%28+1.2%2A6.4+%2B+1.4%2A1.6+%29+%2F+8+=+1.24+\"
\n" ); document.write( "(1) \"+%28+7.68+%2B+2.24+%29+%2F+8+=+1.24+\"
\n" ); document.write( "(1) \"+9.92+%2F+8+=+1.24+\"
\n" ); document.write( "(1) \"+9.92+=+9.92+\"
