$\"1%2F5+%2B+1%2Fx+=+1%2F2\"$ --------------> working eqn
\n" ); document.write( " $\"1%2Fx=1%2F2-1%2F5\"$ , combine similar terms
\n" ); document.write( " $\"1%2Fx=%285-2%29%2F10\"$ , get LCD
\n" ); document.write( " $\"1%2Fx=3%2F10\"$ , cross multiply
\n" ); document.write( " $\"3x=10\"$ , divide 3 to isolate x:
\n" ); document.write( " $\"cross%283%29x%2Fcross%283%29=10%2F3\"$
\n" ); document.write( " $\"x=10%2F3\"$ or \"3-1/3\"
\n" ); document.write( "Check, go back working eqn:
\n" ); document.write( " $\"1%2F5%2B%281%2F%2810%2F3%29%29=1%2F2\"$
\n" ); document.write( " $\"1%2F5%2B3%2F10=1%2F2\"$
\n" ); document.write( " $\"%282%2B3%29%2F10=1%2F2\"$
\n" ); document.write( " $\"5%2F10=1%2F2\"$
\n" ); document.write( " $\"1%2F2=1%2F2\"$
