chair cost = x
\n" ); document.write( "table cost = y\r
\n" ); document.write( "\n" ); document.write( "x= cost of chair
\n" ); document.write( "y= cost of table
\n" ); document.write( "
\n" ); document.write( "-0.07 x + 0.17 y = 296.00 .............1
\n" ); document.write( "Total value
\n" ); document.write( "0.07 x 0.12 y = 400.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -0.12
\n" ); document.write( "Multiply (2) by 0.17
\n" ); document.write( "0.01 x -0.02 y = -35.52
\n" ); document.write( "0.01 x + 0.02 y = 68.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "0.02 x = 32.48
\n" ); document.write( "/ 0.02
\n" ); document.write( "x = 1600.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "-0.07 x + 0.17 y = 296.00
\n" ); document.write( "-112.00 + 0.17 y = 296.00
\n" ); document.write( " 0.17 y = 296.00 + 112.00
\n" ); document.write( " 0.17 y = 408.00
\n" ); document.write( " y = 2400.00
\n" ); document.write( "x= 1600.00 cost of chair
