  1. 4. a set of two or more equations. Each equation contains two or more variables. We want to find values for the variables that make all the equations true.
  2. 6. A term is a part of an expression. It can be a single number, a variable, or a number and a variable that are multiplied together. For example, the expression 5x+18 has two terms. The first term is 5x and the second term is 18.
  3. 7. a variable (often denoted by x ) whose variation does not depend on that of another.
  4. 8. In an expression like 5x+2, the number 2 is called the constant term because it doesn’t change when x changes.
