Well, isn't that just lovely! The addition and subtraction properties of equality help us balance equations by allowing us to add or subtract the same value on both sides. This helps us isolate the variable and find its value, bringing harmony and balance to our mathematical expressions. Just remember, as you work through equations, take your time and enjoy the process of finding solutions.
in an equation like y=5x+3 the 3 would be the y-intercept
Why? - Mainly to help in solving equations.
The addition of the opposite, to both sides of the equation. keep it equal
In mathematics, the equality properties refer to certain rules and properties that govern the behavior of equalities. These properties include the reflexive property (a = a), the symmetric property (if a = b, then b = a), and the transitive property (if a = b and b = c, then a = c). These properties ensure that equality is a well-behaved and consistent relation.
If x=y then x+z=y+z or If x=y and a=b then x+a=y+b The formal name for the property of equality that allows one to add the same quantity to both sides of an equation. This, along with the multiplicative property of equality, is one of the most commonly used properties for solving equations.

The properties are similar in that they function the same way, but they are not interchangeable. If you add to one side of the equation, you have to add to the other. If you subtract from one side of the equation, you have to subtract from the other.

You should state the property used, such as distributive property of multiplication over addition or addition property of equality, etc.
subtract the same 'thing' from both sides of an equality
