when an inequality models a practical problem, why might some of the points on the graph not be solutions to the problem even though they are solutions to the inequality?

Solving equations requires isolating the variable from the other terms of the equation by using the opposite operations. when a number is being added to a variable, you simply need to subtract the number from both sides of the equation. this undoing (or using the opposite operation) allows you to find the numerical value of the variable. solving linear inequalities is very similar to solving equations. you can check your answer to both of these type problems by substituting your answer/s into your initial problem. systems of equations represent several lines. lines can intersect at a point, never intersect because they are parallel, or always intersect since they are the same lines.
hope this i’m not sure but i think my other answer erased?

I’m pretty sure the answer is a
