WebA system has no solutions if two equations are parallel. Let’s take a look at an example. Let's find the solution to the linear system. The first step is to simplify the second equation into y=mx+b form. 2y−8x=10y−4x=5y=4x+5. The coefficients of the variables are the same, so these lines have the same slope. WebSince elementary row operations do not change the solutions of the system, the vectors x which satisfy the simpler system A ′ x = b ′ are precisely those that satisfy the original system, A x = b. Example 3: Solve the following system using Gaussian elimination: The augmented matrix which represents this system is

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 WebFeb 6, 2009 · One way is to look at the graphs of these equations. If they intersect, the point of intersection (x, y) is the only solution of the system. In this case we say that the system is consistent. If their graphs do not intersect, then the system has no solution. In this case we say that the system is inconsistent. If the graph of the equations is the same line, the …
