Write an equation for each statement
\n" ); document.write( ";
\n" ); document.write( " 4 times Harry's age equals 110 minus 3 times Grace's age minus 3 times Dave's age,
\n" ); document.write( "4h = 110 - 3g - 3d
\n" ); document.write( "2 times Grace's age equals 76 minus 2 times Dave's age minus 3 times Harry's age,
\n" ); document.write( "2g = 76 - 2d - 3h
\n" ); document.write( " and 2 times Grace's age equals 68 minus 2 times Dave's age minus 2 times Harry's age.
\n" ); document.write( "2g = 68 - 2d - 2h
\n" ); document.write( ":
\n" ); document.write( "2g = 2g, therefore we can write the equation
\n" ); document.write( "76 - 2d - 3h = 68 - 2d - 2h
\n" ); document.write( "add 2d to both sides
\n" ); document.write( "76 - 3h = 68 - 2h
\n" ); document.write( "76 - 68 = -2h + 3h
\n" ); document.write( "8 = h
\n" ); document.write( "Harry is 8 yrs old
\n" ); document.write( "that is about all I can extract from this problem
\n" ); document.write( " What is each person's age? \n" ); document.write( "
\n" );
