Answer: x > 2.
- A x > 2
- B x < 2
- C x > -2
- D x > 4
Correct answer: A. x > 2
Explanation: 5x - 3x > 1 + 3, so 2x > 4, giving x > 2.
One-variable inequalities use open (excluded) or closed (included) circles on a number line; two-variable inequalities use a dashed (strict) or solid (non-strict) boundary line, with the solution being the entire shaded half-plane on one side of it.
Concept context
Solving linear inequalities in one and two variables algebraically and graphically, and representing solutions on a number line or as a region in a plane.
