WebSolve the system using the inverse matrix method. 1) Solve the system of equations using... Using the inverse matrix method: We can write the system in matrix form as Ax=b, where A = [[-5, 3], [3, -6]] x = [x, y] b = [8, -30] The inverse of A is given by: A^(-1) = 1/(-39) * [[-6, -3], [-1, -5]] So, we can solve for x by multiplying both...
WebSolution Step 1 Put the equation in standard form. We must subtract 6 from both sides. Step 2 Factor completely. Recall how to factor trinomials. Step 3 Set each factor equal to zero and solve for x. Since we have (x - 6) (x + 1) = 0, we know that x - 6 = 0 or x + 1 = 0, in which case x = 6 or x = - 1.
