let b= Bob's age
\n" ); document.write( "let s Sue's age
\n" ); document.write( "let d = Dak's age
\n" ); document.write( ":
\n" ); document.write( "write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "bobs ages four times greater than Susan's age
\n" ); document.write( "b = 4s
\n" ); document.write( ":
\n" ); document.write( "Dakotas three years younger than Susan
\n" ); document.write( "d = s - 3
\n" ); document.write( ":
\n" ); document.write( "the sum of Bob Susan's and Dakotas age is 93
\n" ); document.write( "b + s + d = 93
\n" ); document.write( ":
\n" ); document.write( "what is Susan's age?
\n" ); document.write( "Substitute 4s for b and (s-3) for d, in the above equation
\n" ); document.write( "4s + s + (s-3) = 93
\n" ); document.write( "6s = 93 + 3
\n" ); document.write( "6s = 96
\n" ); document.write( "s = 96/6
\n" ); document.write( "s = 16 yrs is Sue's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "You can check this for yourself, find b and d and see if the sum is 93\r
