Determine number of solutions in system
WebTo solve a system of equations by elimination, write the system of equations in standard form: ax + by = c, and multiply one or both of the equations by a constant so that the coefficients of one of the variables are opposite. Then, add or subtract the two equations to eliminate one of the variables. Solve the resulting equation for the ... Web1 Answer. Sorted by: 6. The null space of an a × b matrix A has dimension b − rank ( A) . The column space has dimension rank ( A). If a system A x = y has infinitely many solutions, the null space must have dimension at least 1. If a system A x = y has one solution, the null space must have dimension 0 and the column space must have ...
