Thus, in the equation x + 3 = 7, the left-hand member is x + 3 and the right-hand member is 7. The terms to the left of an equals sign make up the left-hand member of the equation those to the right make up the right-hand member. Equations such as x + 3 = 7 are first-degree equations, since the variable has an exponent of 1. We call such shorthand versions of stated problems equations, or symbolic sentences. "Find a number which, when added to 3, yields 7"Īnd so on, where the symbols ?, n, and x represent the number we want to find. These techniques involve rewriting problems in the form of symbols. In this chapter, we will develop certain techniques that help solve problems stated in words.
