(1) \"8x+%2B+3y+=+0\"
\n" ); document.write( "(2) \"-x+-+9y+=+92\"
\n" ); document.write( "Subtract \"3y\" from both sides of (1)
\n" ); document.write( "(1) \"8x+=+-3y\"
\n" ); document.write( "Divide both sides by \"-3\"
\n" ); document.write( "(1) \"y+=+-%288%2F3%29%2Ax\"
\n" ); document.write( "Multiply the right side by \"3%2F3\"
\n" ); document.write( "(1) \"y+=+-%2824%2F9%29%2Ax\"
\n" ); document.write( "Substitute this in (2)
\n" ); document.write( "(2) \"-x+-+9y+=+92\"
