let p = Paul's present age
\n" ); document.write( "let r = Ruth's
\n" ); document.write( "let e = Emma's
\n" ); document.write( ":
\n" ); document.write( "Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "Paul's age is three years older than Ruth's age.
\n" ); document.write( " p = r + 3
\n" ); document.write( "or we can write it
\n" ); document.write( " r = p - 3
\n" ); document.write( "If Emma's age is twice that of Paul's age, find out Paul's age
\n" ); document.write( " e = 2p
\n" ); document.write( "if the total of them two years ago was 51 years.
\n" ); document.write( " (p-2) + (r-2) + (e-2) = 51
\n" ); document.write( "Replace r with (p-3) and replace e with 2p
\n" ); document.write( "p-2 + p-3-2 + 2p-2 = 51
\n" ); document.write( "combine like terms
\n" ); document.write( "4p - 9 = 51
\n" ); document.write( "4p = 51 + 9
\n" ); document.write( "4p = 60
\n" ); document.write( "p = 60/4
\n" ); document.write( "p = 15 yrs is Paul's age
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check in the last equation; r = 12, e = 30
\n" ); document.write( "15-2 + 12-2 + 30-2 =
\n" ); document.write( "13 + 10 + 28 = 51 \n" ); document.write( "
\n" );
