### Solving Equations

• A solution to an equation is a number that makes the equation true.
• Equality satisfies the reflexive, symmetric, and transitive properties.
• If both sides of an equation are increased, decreased, multiplied, or divided by the same number, the resulting equation is equivalent to the original one and has the same solutions.
• Use these properties to solve a formula for a variable.
• To solve a word problem, define a variable and create an equation. Then solve that equation.
