SUMMARY
The dimension of the solution space for the equation Ax=0, where A is a 2x3 matrix defined as A = [[1, 2, 5], [-1, 3, 1]], is determined to be 1. This conclusion is reached by applying the formula for the dimension of the solution space, which is calculated by subtracting the rank of matrix A from the number of columns (n). Given that the rank of A is 2 and n is 3, the calculation is 3 - 2 = 1, confirming the dimension of the solution space is indeed 1.
