You can put this solution on YOUR website!
You can solve proportions by cross-multiplying.\r
\n" ); document.write( "\n" ); document.write( "\"65%2F10+=+13%2Fx\" Cross-multiply. This means, multiply both sides by x then multiply both sides by 10.\r
\n" ); document.write( "\n" ); document.write( "\"65x+=+10%2813%29\" Simplify.
\n" ); document.write( "\"65x+=+130\" Divide both sides by 65
\n" ); document.write( "\"x+=+2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "I assume that there is a typo in the second problem and you really meant to type:\r
\n" ); document.write( "\n" ); document.write( "\"3%2F8+=+12%2Fx\" Try this yourself. Cross-multiply, first by x then by 8, then you can solve for x.
