You can put this solution on YOUR website!
Let's try this again, this time keeping track of the negative signs. Assuming the equation you want solved is this:
\n" ); document.write( "\"%28-2%2F3%29%2Ax+-+12+=+0\"
\n" ); document.write( "First, add 12 to both sides:
\n" ); document.write( "\"%28-2%2F3%29%2Ax+-+12+%2B+12+=+0+%2B+12\"
\n" ); document.write( "\"%28-2%2F3%29%2Ax+=+12\"
\n" ); document.write( "Next, divide both sides by \"-2%2F3\", which is the same as multiplying by its reciprocal, \"-3%2F2\"
\n" ); document.write( "\"%28-3%2F2%29%2A%28-2%2F3%29%2Ax+=+%28-3%2F2%29%2A12\"
\n" ); document.write( "\"x+=+%28-3%2A12%29%2F2\"
\n" ); document.write( "\"x+=+-36%2F2\"
\n" ); document.write( "\"x+=+-18\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
