$\"m+=+5s\"$ and $\"2s+=+m%2F2+-3\"$ , by the given.
\n" ); document.write( "Then by direct substitution,
\n" ); document.write( " $\"2s+=+%285s%29%2F2+-+3\"$ . Then,
\n" ); document.write( " $\"3+=+%285s%29%2F2+-2s\"$ ,
\n" ); document.write( " $\"3+=+s%2F2\"$ , and so by cross-multiplication, $\"s+=+6\"$ .
\n" ); document.write( "The mom is $\"m+=+5%2A6+=+30\"$ years old. \n" ); document.write( "
