What property must we use when solving equations?
Addition Property of Equality If two expressions are equal to each other, and you add the same value to both sides of the equation, the equation will remain equal. When you solve an equation, you find the value of the variable that makes the equation true. In order to solve the equation, you isolate the variable.
What are the 4 steps to solving an algebraic equation?
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division. If we add the same number to both sides of an equation, both sides will remain equal.
What are the algebraic properties examples?
This is an example of the Associative Property. Going along with the properties of algebra is the Order of Operations….Algebra Properties.
| Property | Example |
|---|---|
| Commutative | a+b=b+a,ab=ba |
| Associative | a+(b+c)=(a+b)+c,a(bc)=(ab)c |
| Identity | a+0=a,a⋅1=a |
| Inverse | a+(−a)=0,a⋅1a=1 |

What property is it when you flip the equation?
The inverse property of multiplication states that if you multiply a number by its reciprocal, also called the multiplicative inverse, the product will be 1.
What is the first step in solving algebraic expressions?
Step 1: Simplify Each Side of the Equation. As we learned last time, the first step in solving an equation is to make the equation as simple as possible.
