Write a simple equation for each statement:
\n" ); document.write( ":
\n" ); document.write( "\"Joe is 10 years older than James.\"
\n" ); document.write( " Jo = Ja + 10
\n" ); document.write( ":
\n" ); document.write( "\"In 8 years, twice Joe's age will equal three times James's age.\"
\n" ); document.write( "2(Jo + 8) = 3(Ja + 8)
\n" ); document.write( "2Jo + 16 = 3Ja + 24
\n" ); document.write( "2Jo = 3Ja + 24 - 16
\n" ); document.write( "2Jo = 3Ja + 8
\n" ); document.write( ":
\n" ); document.write( "Substitute (Ja+10) for Jo in the above equation, find Ja:
\n" ); document.write( "2(Ja+10) = 3Ja + 8
\n" ); document.write( "2Ja + 20 = 3Ja + 8
\n" ); document.write( "20 - 8 = 3Ja - 2Ja
\n" ); document.write( "Ja = 12 yrs, his age now
\n" ); document.write( ":
\n" ); document.write( "Jo is 10 years older; Jo = 22 yrs now
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the statement:
\n" ); document.write( "\"In 8 years, twice Joe's age will equal three times James's age.\"
\n" ); document.write( "2(22 + 8) = 3(12 + 8)
\n" ); document.write( "2(30) = 3(20)
\n" ); document.write( ":
