1. If John is x years old and Julia is 4 years younger, what age does Alfred have in each case?
\n" ); document.write( "John is x
\n" ); document.write( "Julia is x-4
\n" ); document.write( "--------------------------
\n" ); document.write( "a) Alfred is 1 year older than the average age of John and Julia.
\n" ); document.write( "Alfred = [(x + x-4)/2] + 1 = [(2x-4)/2] + 1 = x-2 + 1 = x-1
\n" ); document.write( "--------------------------------------
\n" ); document.write( "b) Alfred is 2 years younger than 5 times the difference of John's and Julias ages.
\n" ); document.write( "EQUATION:
\n" ); document.write( "x-1 =5(x-(x-4)) -2 = 20-2 = 18
\n" ); document.write( "----------------------------------
\n" ); document.write( "
\n" ); document.write( "This math text is in Spanish so I translated the problems into English.
\n" ); document.write( "2. A father is 3 times as old as his son. In 12 years he will be double the age of his son. What are the father and son's ages now?
\n" ); document.write( "Let son's age be \"x\"; Father's age is \"3x\".
\n" ); document.write( "In 12 yrs, son will ber x+12; father will be \"3x+12\"
\n" ); document.write( "EQUATION:
\n" ); document.write( "3x+12 = 2(x+12)
\n" ); document.write( "x = 12 (son's age)
\n" ); document.write( "3x= 36 (father's age)
\n" ); document.write( "----------------------
