Call Albert's and his father's age NOW, a and f. \n" ); document.write( "Then we have \n" ); document.write( "f = a + 24 \n" ); document.write( "In 8 years, \n" ); document.write( "f + 8 = 2(a + 8) \n" ); document.write( "Now substitute and get \n" ); document.write( "a+24 + 8 = 2(a + 8) \n" ); document.write( "a + 32 = 2a + 16 \n" ); document.write( "Now subtract a from both sides and then subtract 16 and get \n" ); document.write( "32 = a + 16 \n" ); document.write( "a = 16 \n" ); document.write( "Then we have \n" ); document.write( "f = 40 \n" ); document.write( " |
