Inequality Solver
Solve a linear inequality ax + b ⋛ 0.
Worth Knowing
Solving a linear inequality mirrors solving an equation with one crucial twist: multiplying or dividing both sides by a negative number flips the inequality's direction. Forgetting that single rule is the most common mistake in algebra. Unlike an equation's single answer, an inequality's solution is a whole range of values, which is why the result is expressed as an interval rather than one number.
