In the inequality -x > 5, what must you do to solve the problem?
you divide by -5
you divide by 1
you divide by 5
you divide by -1
To solve the inequality -x > 5, you need to divide both sides of the inequality by -1.
To solve the inequality -x > 5, you need to isolate the variable x. To do this, you divide by -1.
To solve the inequality -x > 5, you need to multiply both sides of the inequality by -1. However, it's important to note that when you multiply (or divide) an inequality by a negative number, you must also flip the direction of the inequality sign.
So, in this case, you would divide both sides of the inequality by -1. When you divide -x by -1, the negative signs cancel out and you are left with x. Similarly, when you divide 5 by -1, the negative sign remains, so it becomes -5.
The inequality sign also flips from > to <. Therefore, the solution to the inequality -x > 5 is x < -5.
In summary, to solve the inequality -x > 5, you divide both sides by -1 and flip the inequality sign, resulting in x < -5.
