Adapted Math (Algebra I) Chapter 3 Flashcard

An algebraic equation is a mathematical statement that shows the equality of two expressions, which includes at least one variable.

A variable is a symbol, often a letter, that represents an unknown number in mathematical expressions and equations.

$$x = 61$$ .

Identify the unknown, assign a variable, and express the relationship using an equation.

$$x = 18$$ .

Variables allow us to represent unknown values and formulate equations to solve problems.

Isolating a variable means rearranging an equation so that the variable is on one side and all other terms are on the other side.

A constant is a fixed value that does not change, while a variable represents an unknown value that can change.

A coefficient is a numerical factor that multiplies a variable in an algebraic expression.

$$x + 124 = 159$$ , where x is the weight of the dog.
