3-1 Solving Linear Systems by Graphing
... *A linear system in three variables is an equation in the form ax + by + cz = d where a, b, and c are not all zero. A solution of such a system is an ordered __________________ (x, y, z) whose coordinates make each equation true. The graph is a plane in three-dimensional space. See page 178 for exam ...

... Solving equations involves “undoing” what has been done to create the equation. By systematically working backward, the value of the variable can be found. Multiplication and division are inverse (opposite) operations, as are addition and subtraction. For example, to undo x + 7 = 12, that is, adding ...
