When two secant lines intersect each other outside a circle, the products of their segments are equal.
14(с + 14) = 10(10 + 20)
14с + 196 = 10 * 30
14с +196 = 300
14с = 300 - 196
14с = 104
с = 104/14
с ≈ 7.4
Equalities will have the words "is" or "equals" or "the same as" in the wording. These produce a unique solution.
Inequalities have phrases like "at most" or "at least" or "no more than" in them. Solutions are a range of values, ranging between 2 values, or from a particular value to positive or negative infinity.
