## Study Notes

### Solving Equations

- The first step in solving an equation is to simplify the equation by combining like terms.
- The solution to the equation 3x + 5 = 14 is x = 3, which can be found by subtracting 5 from both sides and then dividing both sides by 3.

### Equation Properties

- If the same value is added to both sides of an equation, the equation remains balanced and its solution is not changed.

### Equations vs. Expressions

- An equation is a statement that says two expressions are equal, whereas an expression is a collection of numbers, variables, and operations combined to produce a value.

### Order of Operations

- The order of operations in solving an equation is to follow the PEMDAS rule: Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction.

### Validating Solutions

- To check if a solution to an equation is valid, plug the solution back into the original equation and verify that the equation is true.
