Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Linear Equations

A linear equation is an algebraic expression that represents a straight line when graphed. It typically takes the form ax + b = c, where a, b, and c are constants. Understanding how to manipulate and solve these equations is essential for finding the value of the variable, in this case, x.

Graphing Calculators

Graphing calculators are powerful tools that allow users to visualize equations and perform complex calculations. They can plot graphs of functions, solve equations, and provide numerical solutions. Familiarity with using a graphing calculator is crucial for efficiently solving linear equations and interpreting their graphical representations.

Distributive Property

The distributive property is a fundamental algebraic principle that states a(b + c) = ab + ac. It allows for the multiplication of a single term across terms within parentheses. In the context of the given equation, applying the distributive property is necessary to simplify the expression before solving for x.
