Hi,
\n" ); document.write( "(3+x):8=x:(1)/(2)
\n" ); document.write( "*Note: write the proportion as follows:
\n" ); document.write( " $\"%283%2Bx%29%2F8+=+x%2F%281%2F2%29\"$
\n" ); document.write( ".
\n" ); document.write( "Cross multiply to solve:
\n" ); document.write( " $\"%281%2F2%29%2A%283%2Bx%29=+8%2Ax\"$
\n" ); document.write( ".
\n" ); document.write( "simplify and solve for x
\n" ); document.write( ".
\n" ); document.write( "(3+x) = 16x
\n" ); document.write( "3 = 15x
\n" ); document.write( "x=(3/15)
\n" ); document.write( "x= (1/5) \n" ); document.write( "

\n" );
