if the average of x, y, and 35 is 20 less than the average of y, z, and 100,
\n" ); document.write( "\"%28x%2By%2B35%29%2F3\" = \"%28y%2Bz%2B100%29%2F3\" - 20
\n" ); document.write( "multiply eq by 3, results
\n" ); document.write( "x + y + 35 = y + z + 100 - 60
\n" ); document.write( "x + y + 35 = y + z + 40
\n" ); document.write( "x + y = y + z + 40 - 35
\n" ); document.write( "x + y = y + z + 5
\n" ); document.write( "Subtract y from both sides
\n" ); document.write( "x = z + 5
\n" ); document.write( "Subtract z from both sides
\n" ); document.write( "x - z = 5\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
