the simultaneous equation is
\n" ); document.write( " 2v = 31 - 3w rewrite to 2v + 3w = 31
\n" ); document.write( " 3v + w = 64 multiply by 3
\n" ); document.write( "then we have
\n" ); document.write( "9v + 3w = 192
\n" ); document.write( "2v + 3w = 31
\n" ); document.write( "---------------subtraction eliminates w, find v
\n" ); document.write( "7v + 0 = 161
\n" ); document.write( "v = 161/7
\n" ); document.write( "v = 23
\n" ); document.write( ":
\n" ); document.write( "Find w using the equation 3v + w = 64, replace v with 23
\n" ); document.write( "3(23) + w = 64
\n" ); document.write( "69 + w = 64
\n" ); document.write( "w = 64 - 69
\n" ); document.write( "w = -5
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check these solutions in the equation 2v = 31 - 3w
\n" ); document.write( "2(23) = 31 - 3(-5)
\n" ); document.write( "46 = 31 + 15
\n" ); document.write( " \n" ); document.write( "
\n" );
