Linear Equations in x

EngageNY 45 min(s)

Students know that a linear equation is a statement of equality between two expressions. Students know that a linear equation in 𝑥 is actually a question: Can you find all numbers 𝑥, if they exist, that satisfy a given equation? Students know that those numbers that satisfy a given equation are called solutions. Using what you know about the words linear and equation, develop a mathematical definition of "linear equation in 𝑥."
