- In Exercises 7–10, the augmented matrix of a linear system hasbeen reduced by row operations to the form shown. In each case,continue the appropriate row operations and describe the solutionset of the original systemarrow_forward11 3 4 12 21 45, For what values of a, does the linear system Az = b have no solution? Let A = 1 2 -11 and b = 3arrow_forwardIn Exercises 13–17, determine conditions on the bi ’s, if any, in order to guarantee that the linear system is consistent. 13. x1 +3x2 =b1 −2x1 + x2 =b2 15. x1 −2x2 +5x3 =b1 4x1 −5x2 +8x3 =b2 −3x1 +3x2 −3x3 =b3 14. 6x1 −4x2 =b1 3x1 −2x2 =b2 16. x1 −2x2 − x3 =b1 −4x1 +5x2 +2x3 =b2 −4x1 +7x2 +4x3 =b3 17. x1 − x2 +3x3 +2x4 =b1 −2x1 + x2 + 5x3 + x4 = b2 −3x1 +2x2 +2x3 − x4 =b3 4x1 −3x2 + x3 +3x4 =b4arrow_forward
- Please show solutionarrow_forward4. Use Gaussian elimination with backward substitution to solve the following linear system: 2x1 + x2 – x3 = 5, x1 + x2 – 3x3 = -9, -x1 + x2 + 2x3 = 9;arrow_forwardWrite the difference equations in Exercises and as first-order systems, xk+1 = Axk, for all k. yk+4 - 6yk +3 + 8 yk +2 + 6yk+1 - 9yk = 0arrow_forward
- 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_forwardExercise 3.3.2. a) Verify that the system =31has the two solutions e4t and 1e-2. b) Write down the general solution. c) Write down the general solution in the form x?, x2 ? (i.e. write down a formula for each element of the solution)arrow_forward7. Solve the linear system using the Cramer's Rule and Gaussian elimination. -8x + 27 = 1 6y + 4z = 3 12x + 2y = 2arrow_forward
