\n" ); document.write( "\n" ); document.write( "        I came to bring a correct solution.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let Colleen's age be x years.
\n" ); document.write( "Then Craig age is (x+4) years.         (Craig is 4 years older than Colleen)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + (x+4) = 76         (their combined age)
\n" ); document.write( "2x + 4 = 76
\n" ); document.write( "2x = 76 - 4
\n" ); document.write( "2x = 72
\n" ); document.write( "x = 72/2
\n" ); document.write( "x = 36
\n" ); document.write( "So Colling is 36 years old and Craig is 36 + 4 = 40 years old.         ANSWER\r
