The ages of Paul and Judy total 27 years
\n" ); document.write( "Judy's age plus twice Paul' age is 43
\n" ); document.write( "First translate the words into an algebra equation
\n" ); document.write( "----------------
\n" ); document.write( "Use P for Paul's age and J for Judy's age. It saves typing.
\n" ); document.write( "The 1st sentence says P + J = 27. So far so good.
\n" ); document.write( "Then the 2nd sentence:
\n" ); document.write( "J + 2*P = 43 See that?
\n" ); document.write( "Now we have 2 eqns in 2 unknowns, so we can solve for P and J (not PB & J, tho)
\n" ); document.write( "---------
\n" ); document.write( "J + P = 27 EQN 1
\n" ); document.write( "J + 2P = 43 EQN 2
\n" ); document.write( "Subtract EQN 1 from EQN 2
\n" ); document.write( "0 + P = 16
\n" ); document.write( "So Paul is 16
\n" ); document.write( "27 - 16 = 11, so
\n" ); document.write( "Jane is 11.\r
\n" ); document.write( "\n" ); document.write( "That's it.
\n" ); document.write( "
\n" );
