Unformatted text preview: PART B: SOLVING EQUATIONS A solution to an equation in x is a number that makes the equation true when the number is substituted for x . • For now, we only consider real solutions. We solve an equation by finding its solution set , the set of all solutions. When solving an equation, we often write a sequence of equivalent equations , which have the same solution set . • Adding, subtracting, multiplying, and dividing the same nonzero number on both sides of an equation maintains equivalence....
