Sherman's age and his grandpa's age together equal 72. His grandpa's age is 7 times greater than his age. How old are they.
\n" ); document.write( "-------------
\n" ); document.write( "Let Sherman be x yrs. old
\n" ); document.write( "Then grandpa is 7*x = 7x yrs. old
\n" ); document.write( "-------------------------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "Sherman's age + Grandpa's age = 72
\n" ); document.write( "x + 7x = 72
\n" ); document.write( "8x = 72
\n" ); document.write( "Divide both sides by 8 to get :
\n" ); document.write( "x = 9 yrs. (Sherman's age)
\n" ); document.write( "7x = 63 yrs. (Grandpa's age)
\n" ); document.write( "-------------------------
