b = B's present age

\n" ); document.write( ":
\n" ); document.write( "\"Brianne is three times as old as Camila.\"
\n" ); document.write( "b = 3c
\n" ); document.write( ":
\n" ); document.write( "\" Four years from now she will be just two times as old as Camila.\"
\n" ); document.write( "b + 4 = 2(c+4)
\n" ); document.write( "b + 4 = 2c + 8
\n" ); document.write( "b = 2c + 8 - 4
\n" ); document.write( "b = 2c + 4
\n" ); document.write( "Replace b with 3c
\n" ); document.write( "3c = 2c + 4
\n" ); document.write( "3c - 2c = 4
\n" ); document.write( "c = 4 yrs is C's present age
