D) Expression; $5 x+2$

Quizplus · Accepted Answer

This is an equation because it includes an equals sign, indicating a relationship between two expressions that needs to be solved for $x$. Simplifying and solving: $7x - (5x - 1) = 2$ becomes $7x - 5x + 1 = 2$, which simplifies to $2x = 1$, and solving for $x$ gives $x = \frac{1}{2}$.
