For the following system of linear equations: I1 + 2x₂ 3 −1₁+1₂ = 3 4x₁+5x₂ = 6 = (a) Write the augmented matrix for this system. (b) Use Gaussian elimination (GE) or Gauss-Jordon elimination (GJ) on the augmented matrix to get a row-equivalent matrix in row-echelon (RE) or reduced row-echelon (RRE) form and solve the system. Clearly indicate each of your GE or GJ steps. For example, if you add 2 x row 1 to row 2, you'd write that as "R₂+2R₁ → R₂” and then show your resulting matrix. (c) Is the system consistent or inconsistent?

Question
Transcribed Image Text:For the following system of linear equations:
*1 + 2x₂
-x1 + x₂
4x1 + 5x2
= 3
= 3
= 6
(a) Write the augmented matrix for this system.
(b) Use Gaussian elimination (GE) or Gauss-Jordon elimination (GJ) on the augmented
matrix to get a row-equivalent matrix in row-echelon (RE) or reduced row-echelon (RRE)
form and solve the system. Clearly indicate each of your GE or GJ steps. For example,
if you add 2 x row 1 to row 2, you'd write that as "R2+2R1 → R₂" and then show your
resulting matrix.
(c) Is the system consistent or inconsistent?
