WebOct 14, 2024 · You just have to pick x = y = 1, then you get s = t = 2 to get a possible solution. denote the unknown matrix you want to find. First equation say that − 8 a + 4 c = 0 in other words 8 a = 4 c which further implies that c = 2 a. similarly you can use the third equation to conclude that d = 2 b. WebThis section is about solving the \matrix equation" Ax = b, where A is an m n matrix and b is a column vector with m entries (both given in the question), and x is an unknown column vector with n entries (which we are trying to solve for). The rst thing to know is what Ax means: it means we are multiplying the matrix A times the vector x.
