Step-by-step explanation:

To solve equations, we use inverse operations. Normally, we use PEMDAS to simplify an equation. To solve it, we use the inverse of each in this order SADMEP. Solving an inequality is the same except for step. When dividing by a negative, the sign of the inequality changes.

We have in simplified form. We begin by subtracting or adding constants across the equal sign. Then doing the same with the variable terms. We finish by dividing by the coefficient of the variable term.

To graph, we draw a number line, draw an open circle at -3.

Since it is not equal to, we do not fill it in. We leave it open. We also draw an arrow to the right of -3
