Let C = Chanda's age now
\n" ); document.write( "Let S = Suzanne's age now
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"Chanda is now four times old as her sister Suzanne.\"
\n" ); document.write( "C = 4S
\n" ); document.write( ";
\n" ); document.write( "\"Next year, Chanda's age will be three times Suzanne's age then.\"
\n" ); document.write( "C + 1 = 3(S + 1)
\n" ); document.write( ":
\n" ); document.write( "C + 1 = 3S + 3
\n" ); document.write( ":
\n" ); document.write( "C = 3S + 3 - 1
\n" ); document.write( ":
\n" ); document.write( "C = 3S + 2
\n" ); document.write( ":
\n" ); document.write( " How old is each now?
\n" ); document.write( ":
\n" ); document.write( "From the 1st equation substitute 4S for C in the above equation
\n" ); document.write( "4S = 3S + 2
\n" ); document.write( ":
\n" ); document.write( "4S - 3S = 2
\n" ); document.write( ":
\n" ); document.write( "S = 2 yrs is Suzanne's age now
\n" ); document.write( ":
\n" ); document.write( "You figure out C's age \n" ); document.write( "
\n" );
