Determining Whether a System of Equations Has No …

WebIt has no solution, because x >= 0. That is, when we take the absolute value of any number x, we get zero (for x = 0) or a positive number (for x not equal to zero). The absolute value of x, x , can never be negative, so it can never satisfy this inequality. Thus, x < 0 has no solution. Example 2: Absolute Value Inequality With No Solution WebThere are a few ways to tell when a linear system in two variables has one solution: Solve the system – if you solve the system and get a single equation (such as x = 2 and y = 5), then there is one solution. Look at the graph – if the two lines have different slopes (they intersect exactly once), then there is one solution to the system. green lake wi post office
