Algebra. + x Solution Solution Solution Solution Solution. Except where otherwise noted, textbooks on this site In the augmented matrix the first equation gives us the first row, the second equation gives us the second row, and the third equation gives us the third row. Compound inequalities are also called 'and/or,' 'and & or,' and 'and-or' inequalities. 3 3 Once you have solved each part, graph the inequalities on the same number line. This is a compound inequality because it uses the word 'and.' 2 y 2 = 5 She has recently earned a Master's degree. x x Once a system of equations is in its augmented matrix form, we will perform operations on the rows that will lead us to the solution.
