Hi there,
\n" ); document.write( "Make the child's age = 'x'
\n" ); document.write( "In 10 years, a child's age will be 4
\n" ); document.write( "years less than triple her current age.
\n" ); document.write( "x + 10 = 3x - 4
\n" ); document.write( "Collect like terms
\n" ); document.write( "x - 3x = - 4 - 10
\n" ); document.write( "-2x = - 14
\n" ); document.write( "x = 7
\n" ); document.write( "Child's current age is 7 yrs old.
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "

\n" );
