  Mathematics includes many different kinds of algebraic expressions to solve problems, An equation with two unknown quantities, for instance, is written x+y=20. If there in no condition, for instance, is no condition given to the problem, this equation has many possible solutions, such as x=14 and y=6; x=12 and y=8; and so on. However, when a further condition is given, the possible number of solutions can be reduced. For example, if the condition says that x and y are identical, x and y must each equal                      .
