How to fill out solving inequalities by addition

How to Fill Out Solving Inequalities by Addition:

1. Start by identifying the inequality sign. Is it greater than (>) or less than (<)? This will determine the direction of the solution.
2. Next, isolate the variable term on one side of the inequality. If there are any constant terms on that side as well, move them to the other side of the inequality by performing the opposite operation. For example, if you have "2x + 5 > 9," subtract 5 from both sides to get "2x > 4."
3. Divide both sides of the inequality by the coefficient of the variable term to solve for the variable. In the previous example, divide both sides of "2x > 4" by 2 to get "x > 2."
4. The solution is not just a single value but a range of values since it is an inequality. So, use brackets or parentheses to represent the interval. If the inequality sign is greater than (>) or greater than or equal to (≥), use a square bracket [ or square bracket with a line underneath as in [_. If it is less than (<) or less than or equal to (≤), use a round bracket ( or round bracket with a line underneath as in (_. In our example, the solution would be "x > 2" or "[2, ∞)".
