Let \"+x+\" = her mother's age
\n" ); document.write( "\"+x+%2B+5+\" = her father's age
\n" ); document.write( "\"+%281%2F2%29%2Ax+\" = the girl's age
\n" ); document.write( "---------------------------
\n" ); document.write( "\"+x+%2B+x+%2B+5+%2B+%281%2F2%29%2Ax+=+100+\"
\n" ); document.write( "\"+2x+%2B+%281%2F2%29%2Ax+=+100+-+5+\"
\n" ); document.write( "Multiply both sides by \"+2+\"
\n" ); document.write( "\"+4x+%2B+x+=+2%2A95+\"
\n" ); document.write( "\"+5x+=+190+\"
\n" ); document.write( "\"+x+=+38\"
\n" ); document.write( "and
\n" ); document.write( "\"+%281%2F2%29%2Ax+=+19+\"
\n" ); document.write( "and
\n" ); document.write( "\"+x+%2B+5+=+43+\"
\n" ); document.write( "--------------------
\n" ); document.write( "The girl is 19
\n" ); document.write( "Her mother is 38
\n" ); document.write( "Her father is 43
\n" ); document.write( "
\n" ); document.write( "
