x= Investment in B
\n" ); document.write( "y= Investment in A
\n" ); document.write( "
\n" ); document.write( "1.00 x -1.00 y = 4,000.00 .............1
\n" ); document.write( "Total value
\n" ); document.write( ".07 x .02 y = 1,360.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1.00
\n" ); document.write( "Multiply (2) by 50.00
\n" ); document.write( "1.00 x -1.00 y = 4,000.00
\n" ); document.write( "3.50 x + 1.00 y = 68,000.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "4.50 x = 72,000.00
\n" ); document.write( "/ 4.50
\n" ); document.write( "x = 16,000.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1.00 x -1.00 y = 4,000.00
\n" ); document.write( "16,000.00 -1.00 y = 4,000.00
\n" ); document.write( " -1.00 y = 4,000.00 -16,000.00
\n" ); document.write( " -1.00 y = -12,000.00
