The inequalities define the conditions that are to be considered simultaneously. This inequality solution was often formatted as being half of a number line; for this inequality, it would be the left-hand half of the number line, being all the numbers that are less than 4. For the inequality to interval notation converter, first choose the inequality type: One-sided; Two-sided; or; Compound, See how to turn a word problem into an inequality. In solving equations, we use the above property to produce equivalent equations in which the variable has a coefficient of 1. How do I solve linear inequalities? To solve linear inequalities, isolate the variable on one side of the inequality, keeping track of the sign of the inequality when multiplying or dividing by a negative number, and express the solution as an interval. This can be formulated as a constrained minimization problem, similar to this answer: In this example, we have a strict inequality.
