Answer 1

Answer:

In the solution of problems, by means of equations, two things are necessary: First, to translate the statement of the question from common to algebraic language, in such a manner as to form an equation: Secondly, to reduce this equation to a state in which the unknown quantity will stand by itself, and its value be given in known terms, on the opposite side. The manner in which the latter is effected, has already been considered.
