Let $\"+j+\"$ = Janet's age now
\n" ); document.write( "Let $\"+m+\"$ = mother's age now
\n" ); document.write( "----------------------------
\n" ); document.write( "given:
\n" ); document.write( "(1) $\"+m+=+2j+%2B+10+\"$
\n" ); document.write( "(2) $\"+m+=+30+\"$
\n" ); document.write( "--------------------
\n" ); document.write( "Substitute (2) into (1)
\n" ); document.write( "(1) $\"+30+=+2j+%2B+10+\"$
\n" ); document.write( "Subtract $\"+10+\"$ from both sides
\n" ); document.write( "(1) $\"+30+-+10+=+2j+\"$
\n" ); document.write( "(1) $\"+2j+=+20+\"$
\n" ); document.write( "Divide both sides by $\"+2+\"$
\n" ); document.write( "(1) $\"+j+=+10+\"$
\n" ); document.write( "Janet is 10
\n" ); document.write( "----------------
\n" ); document.write( "check:
\n" ); document.write( "Janet's mother is 10 years more than twice Janets age
\n" ); document.write( "Twice Janet's age is: $\"+20+\"$
\n" ); document.write( "Mother is $\"+10+\"$ more than that, or $\"+30+\"$
\n" ); document.write( "OK
\n" ); document.write( " \n" ); document.write( "
