Question

) Condition for lines having unique solution is a) 1 2 = 1 2 b) 1 2 ≠ 1 2 c) 1 2 = 1 2 ≠ 1 2 d) none of these

Answer 1

Answer:

The example shown previously in this module had a unique solution. The structure of the row reduced matrix was

∣∣∣∣∣100110−1−51|||58−1∣∣∣∣∣

and the solution was

x=1

y=3

z=−1

As you can see, each variable in the matrix can have only one possible value, and this is how you know that this matrix has one unique solution

No solution

Let’s suppose you have a system of linear equations that consist of:

x+y+z=2

y−3z=1

2x+y+5z=0
