Answer:
An example of a situation that you might not be able to use an equation with a single unknown is
[tex]x = \ln{e^x}[/tex]
Step-by-step explanation:
An example of a situation that you might not be able to use an equation with a single unknown is
[tex]x = \ln{e^x}[/tex]
The identity on both sides which results in 1 = 1 and thus the equation is not usable.
An example of an equation which isn't understandable with a single variable is one which doesn't provide a valid value for the value or has no solution. Hence, an example is 7x - 3x + 6 = x + 3x + 8
Collecting like terms
7x - 3x - x - 3x = 8 - 6
0 = - 2
There is no solution for the variable in the stated equation.
This equation is not invalid or may be missing a certain variable in other to make it correct or sensible.
Hence, the equation isn't understandable with a single variable.
