- Consider the system of linear equations in x and y. ax+by=ecx+dy=f Under what conditions will the system have exactly one solution?arrow_forwardSolve this system for x and y in terms of b, and explain why a small change in b(for b near 2) produces a large change in x and y.arrow_forwardI am confused with how to find the general solution of the matrix for problem 14. In this problem the general solution matrix is [-1/2 1 0],but I don't understand why that would be the general solution.arrow_forward
- Consider the initial value problem x' = 3x - 2y, x(0) = 3; y' = 5x - 4y, y(0) = 6, Provide exact solution of the system?arrow_forwardFor each of the following linear systems, either solve1 the linear system or show that it has no solutions. Use Gaussian elimination in each case, reducing to RREF (if possible) and reading off any solutions from the matrix. (a) x+ 2y − z = 2, 2x + y = 6, x − y + z = 3 b) 3x − 2y + z = −2, x − y + 3z = 5, −x + y + z = −1 (c) x1 + x3 = 4, x1 − x2 + 2x3 = 5, 4x1 − x2 + 5x3 = 17arrow_forward
