Find the solution set. Write the solution set in interval notation and graph it on a number line.
We start by removing parentheses:
After combining like terms, we have
Now we can add to both sides:
The variables have disappeared and we are left with a statement that is always false ( a contradiction). This means that the original inequality is always false. There are no solutions. The solution is the empty set, . There is no interval or graph for the empty set.
