If you started with:
\n" ); document.write( " x + y = 48
\n" ); document.write( "12x + 14y = 628
\n" ); document.write( ".
\n" ); document.write( "Start by reordering:
\n" ); document.write( "12x + 14y = 628
\n" ); document.write( " x + y = 48
\n" ); document.write( ".
\n" ); document.write( "Now, multiply both sides of the second equation by -12:
\n" ); document.write( " 12x + 14y = 628
\n" ); document.write( "-12(x + y) = -12(48)
\n" ); document.write( ".
\n" ); document.write( " 12x + 14y = 628
\n" ); document.write( " -12x + (-12y) = -576
\n" ); document.write( ".
\n" ); document.write( "Now, we're ready to combine equation 1 with equation 2:
\n" ); document.write( " 12x + 14y = 628
\n" ); document.write( " -12x + (-12y) = -576
\n" ); document.write( "-----------------------
\n" ); document.write( " 2y = 52
\n" ); document.write( " y = 26 (solution for y)
\n" ); document.write( ".
\n" ); document.write( "Use the above definition of y and plug it back into:
\n" ); document.write( " x + y = 48
\n" ); document.write( "to solve for 'x'.
\n" ); document.write( ".
\n" ); document.write( " x + y = 48
\n" ); document.write( " x + 26 = 48
\n" ); document.write( " x = 48-26
\n" ); document.write( " x = 22 (solution for x)
\n" ); document.write( "
\n" );
