Question: Given the equation 0.5x1 x2 = 9.5 1.02x1 2x2 = 18.8 (a) Solve graphically. (b) Compute the determinant. (c) On the

Given the equation

0.5x1 – x2 = – 9.5

1.02x1 – 2x2 = – 18.8

(a) Solve graphically.

(b) Compute the determinant.

(c) On the basis of (a) and (b), what would you expect regarding the system’s condition?

(d) Solve by the elimination of unknowns.

(e) Solve again, but with α11 modified slightly to 0.52. Interpret your results.
