1. The problem is to solve the inequality $$670 - 37 \leq 78$$ and express the solution in interval form with two decimal places. 2. First, simplify the left side: $$670 - 37 = 633$$ 3. Now the inequality is: $$633 \leq 78$$ 4. This inequality is false because 633 is not less than or equal to 78. 5. Therefore, there is no value of $x$ that satisfies this inequality. 6. The solution set is the empty set, which in interval notation is: $$\emptyset$$
