This is an example of an inequality relation in mathematical notation, where the less-than symbol "<" is used to show that the left-hand side (LHS) of the inequality is less than the right-hand side (RHS). In the given inequality, 63 is the LHS and 7x is the RHS, where x is an unknown quantity.
From the inequality, we can deduce that 7x > 63, or that x > 63/7. This means that the value of x must be greater than 8.857.
