Examples of Consistent Simultaneous Equations
Arbitrary Example $1$
Consider the simultaneous equations:
\(\ds x + y\) | \(=\) | \(\ds 10\) | ||||||||||||
\(\ds x + 2 y\) | \(=\) | \(\ds 15\) |
These are satisfied with the values:
\(\ds x\) | \(=\) | \(\ds 5\) | ||||||||||||
\(\ds y\) | \(=\) | \(\ds 5\) |
and so are consistent.
Arbitrary Example $2$
Consider the simultaneous equations:
\(\ds x + y\) | \(=\) | \(\ds 10\) | ||||||||||||
\(\ds x + y\) | \(=\) | \(\ds 15\) |
These cannot be satisfied by any pair of values for $x$ and $y$.
Hence they are inconsistent.
