(500x+100y=325)
\n" ); document.write( " (400x+150y=304)
\n" ); document.write( "Simplify each equation so we can use elimination
\n" ); document.write( "divide the 2nd equation by 40 and the 1st equation by 50
\n" ); document.write( "10x + 3.75y = 7.6
\n" ); document.write( "10x + 2.0y = 6.5
\n" ); document.write( "-------------------subtraction eliminates x, find y
\n" ); document.write( "0 + 1.75y = 1.1
\n" ); document.write( "y = 1.1/1.75
\n" ); document.write( "y = .62857
\n" ); document.write( "Use the first equation to find x
\n" ); document.write( "500x = 100(.62857) = 325
\n" ); document.write( "500x = 325 - 62.857
\n" ); document.write( "500x = 262.143
\n" ); document.write( "x = 262.143/500
\n" ); document.write( "x = .52429
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "See if this checks out in the 2nd equation
\n" ); document.write( "400(.52429) + 150(.62857) =
\n" ); document.write( "209.7144 + 94.2855 = 303.9999 ~ 304 \n" ); document.write( "
