The starting equation is 9y-8=19.9
Add eight on both sides 9y=27.9
Divide by nine y=3.1
The final answer is y = 3.1
A rational number stops and can be turned into a fraction and doesn’t repeat while an irrational number does the opposite
5a, because both are divided by 5 as the greatest common factor, and a to the first power (not a squared or cubed) is the greatest variable power they share :)
