\n" ); document.write( "P=Peter's age; J=John's age
\n" ); document.write( ".
\n" ); document.write( "A).
\n" ); document.write( "P-J=(5x-4)-(2x+1)=3x-5 .
\n" ); document.write( "ANSWER A): Peter is 3x-5 older than John.
\n" ); document.write( ".
\n" ); document.write( "B).
\n" ); document.write( "10=3x-5
\n" ); document.write( "15=3x
\n" ); document.write( "5=x
\n" ); document.write( ".
\n" ); document.write( "I).
\n" ); document.write( "ANSWER I): Value of x is 5.
\n" ); document.write( ".
\n" ); document.write( "II).
\n" ); document.write( "P=5x-4=5(5)-4=25-4=21 .
\n" ); document.write( "ANSWER IIA). Peter is 21 years old.
\n" ); document.write( "J=2x+1=2(5)+1=10+1=11 .
\n" ); document.write( "ANSWER IIB). John is 11 years old.
