The inverse of a matrix
... Ways to find the inverse of a matrix There are several possible ways to get the inverse A–1 of a matrix A: On your calculator: Enter matrix [A], then calculate [A]–1 (you must use the key for the -1). [See page 236 Example 2, and the calculator instructions on page 269.] Using row operations: ...

A5 Simultaneous equations
... The elimination method If two equations are true for the same values, we can add or subtract them to give a third equation that is also true for the same values. For example, suppose 3x + y = 9 5x – y = 7 Adding these equations: 3x + y = 9 + 5x – y = 7 8x divide both sides by 8: ...
