One can know if an equation is extraneous if after plugging it in the original equation, it shows a false meaning or the value is undefined.
<h3>What is an extraneous equation?</h3>
It should be noted that an extraneous equation means a root of a transformed equation that isn't the root of the original equation due to the fact that it's excluded from the domain of the original equation.
In this case, one can know if an equation is extraneous if after plugging it in the original equation, it shows a false meaning or the value is undefined.

Step-by-step explanation:
Number of red balloons = 17
Number of purple balloons = 11
Number of orange balloons = 3
Number of green balloons = 1

Adding four and subtracting one is the same as adding three. So, to see if a number can be in this pattern, subtract five and check if the result is a multiple of three. If it is, it can be in the pattern.
Fun fact: to check if something is a multiple of three, add all the digits up and see if that is a multiple of three. If you don’t know, repeat the process of adding the digits.
