Mother's age = x
\n" ); document.write( "Girl's age = x/2
\n" ); document.write( "Father's age = x + 5
\n" ); document.write( "x/2 + x + (x + 5) = 100
\n" ); document.write( "x/2 + x + x + 5 = 100
\n" ); document.write( "Common denominator = 2
\n" ); document.write( "x + 2x + 2x + 10 = 200
\n" ); document.write( "5x + 10 = 200
\n" ); document.write( "5x = 190
\n" ); document.write( "x = 38
