write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "jo's age plus mo's age is 27
\n" ); document.write( "j + m = 27
\n" ); document.write( ":
\n" ); document.write( "and jo's age plus flo's age is 38
\n" ); document.write( "j + f = 38
\n" ); document.write( ":
\n" ); document.write( " and mo's age plus flo's age is 33.
\n" ); document.write( "m + f = 33
\n" ); document.write( ":
\n" ); document.write( "Add the three equations
\n" ); document.write( "j + m + 0 = 27
\n" ); document.write( "j + 0 + f = 38
\n" ); document.write( "0 + m + f = 33
\n" ); document.write( "--------------------
\n" ); document.write( "2j + 2m + 2f = 98
\n" ); document.write( "simplify, divide by 2
\n" ); document.write( "j + m + f = 49
\n" ); document.write( "We know j+m = 27
\n" ); document.write( "27 + f = 49
\n" ); document.write( "f = 49 - 27
\n" ); document.write( "f = 22 is flo's age
\n" ); document.write( "then replace f
\n" ); document.write( "m + 22 = 33
\n" ); document.write( "m = 33-22
\n" ); document.write( "m = 11 is Moe's age
\n" ); document.write( "and replace m
\n" ); document.write( "j + 11 = 27
\n" ); document.write( "j = 27 - 11
\n" ); document.write( "j = 16 yrs is joe's age
\n" ); document.write( ":
