Linear Equations and Matrices

Section 1.1, p. 8
2. x = 1, y = 2, z = −2.

4. No solution.

6. x = 13 + 10t, y = −8 − 8t, t any real number.

8. Inconsistent; no solution.

10. x = 2, y = −1.

12. No solution.

14. x = −1, y = 2, z = −2.
16. (a) For example: s = 0, t = 0 is one answer.
(b) For example: s = 3, t = 4 is one answer.
(c) s = 2t .

18. Yes. The trivial solution is always a solution to a homogeneous system.

20. x = 1, y = 1, z = 4.

22. r = −3.

24. If x1 = s1 , x2 = s2 , . . . , xn = sn satisfy each equation of (2) in the original order, then those
same numbers satisfy each equation of (2) when the equations are listed with one of the original ones
interchanged, and conversely.

25. If x1 = s1 , x2 = s2 , . . . , xn = sn is a solution to (2), then the pth and qth equations are satisfied.
That is,

ap1 s1 + · · · + apn sn = bp
aq1 s1 + · · · + aqn sn = bq .

Thus, for any real number r,

(ap1 + raq1 )s1 + · · · + (apn + raqn )sn = bp + rbq .

Then if the qth equation in (2) is replaced by the preceding equation, the values x1 = s1 , x2 = s2 , . . . ,
xn = sn are a solution to the new linear system since they satisfy each of the equations.
