Example 1
easyIn , is the second equation redundant?
Solution
- 1 Step 1: Divide equation 2 by 2: .
- 2 Step 2: This is identical to equation 1.
- 3 Step 3: Yes, equation 2 adds no new information — it is redundant.
Answer
Yes, equation 2 is redundant.
A redundant equation is a scalar multiple of another equation (or a linear combination of other equations). It doesn't reduce degrees of freedom or constrain the solution further.
