An important method for solving equations is to ﬁnd a
sequence of equivalent equations that starts with the given
equation and ends with an equation whose solutions are easy
An equation of the form x = a, where a is a real number, is
an equation whose only solution is obvious.
Suppose A, B, and C are algebraic expressions.
If A = B then A + C = B + C .
If A = B then AC = BC .
If A = B and C = 0, then A
