Write an equation for each statement
\n" ); document.write( ":
\n" ); document.write( "\"Bob is 24 years younger than his father.\"
\n" ); document.write( " B = F - 24
\n" ); document.write( ":
\n" ); document.write( "\"In 2 years he will be half as old as his father.\"
\n" ); document.write( " B + 2 = .5(F + 2)
\n" ); document.write( " B + 2 = .5F + 1
\n" ); document.write( " B = .5F + 1 - 2
\n" ); document.write( " B = .5F - 1
\n" ); document.write( ":
\n" ); document.write( "How old is each now?
\n" ); document.write( "Substitute (F-24) for B in the above equation
\n" ); document.write( "F - 24 = .5F - 1
\n" ); document.write( ":
\n" ); document.write( "F = .5F - 1 + 24
\n" ); document.write( ":
\n" ); document.write( "F -.5F = 23
\n" ); document.write( ":
\n" ); document.write( ".5F = 23
\n" ); document.write( ":
\n" ); document.write( "F = 23/.5
\n" ); document.write( ":
\n" ); document.write( "F = 46 yrs is Father's ate now
\n" ); document.write( "Then
\n" ); document.write( "46 - 24 = 22 yrs is Bob's age now
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution in the statement:
\n" ); document.write( "\"In 2 years he will be half as old as his father.\"
\n" ); document.write( " 22 + 2 = .5(46+2)
\n" ); document.write( " 24 = 24; confirms our solution \n" ); document.write( "
\n" );
