x= hot dogs
\n" ); document.write( "y= soda
\n" ); document.write( "Total sold
\n" ); document.write( "1 x + 1 y = 87 .............1
\n" ); document.write( "
\n" ); document.write( "2 x 0.50 y = 78.50 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -0.50
\n" ); document.write( "Multiply (2) by 1.00
\n" ); document.write( "-0.50 x -0.50 y = -43.50
\n" ); document.write( "2 x + 0.50 y = 78.50
\n" ); document.write( "Add the two equations
\n" ); document.write( "1 x = 35.00
\n" ); document.write( "/ 1
\n" ); document.write( "x = 35.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 1 y = 87
\n" ); document.write( "35 + y = 87
\n" ); document.write( " y = 87 -35
\n" ); document.write( " y = 52
\n" ); document.write( " y = 52.00
\n" ); document.write( "x= 35 hot dogs
\n" ); document.write( "y= 52 soda
