To solve the equation y-40=40, we can use the following steps:
- Add 40 to both sides of the equation, which gives us y-40+40=40+40
- Simplify the equation, which gives us y=80
Therefore, the solution of the equation is y=80.
The axiom that we use here is Euclid's second axiom, which states that if equals are added to equals, the wholes are equal¹²³. This means that we can perform the same operation on both sides of an equation without changing its solution.
