Hi there,
\n" ); document.write( "Isabel is 6 years older than marie
\n" ); document.write( "I = 6 + M
\n" ); document.write( "In 4 years, isabels age will be
\n" ); document.write( "9 years less than twice maries age.
\n" ); document.write( "I + 4 = 2(M + 4)- 9
\n" ); document.write( "I + 4 = 2M + 8 - 9
\n" ); document.write( "Replace I with (6 + M) from equation above.
\n" ); document.write( "6 + M + 4 = 2M + 8 - 9
\n" ); document.write( "Collect like terms
\n" ); document.write( "M - 2M = -1 - 10
\n" ); document.write( "-M = -11
\n" ); document.write( "M = 11
\n" ); document.write( "Marie is 11 years old
\n" ); document.write( "Isabel is 17 years old.
\n" ); document.write( "Hope this helps:-) \n" ); document.write( "
