Sign In
What can you do to isolate a variable in an inequality?
I
Inequalities can be solved in the same way as equations, by performing inverse operations on both sides until the variable is isolated. The only difference is that when multiplying or dividing by a negative number, the inequality sign must be reversed.
The above tells us that all values greater than - 2 will satisfy the inequality. This corresponds with answer I.
