Answer:
12
Explanation:
Key first step: 9 - 4 can be simplified to 5! Once you do this, the entire thing becomes much less intimidating.
We now have 2 * 7 - (10 / 5), simplify (10 / 5) to 2.
We now have 2 * 7 - 2, simplify 2 * 7 to 14.
We now have 14 - 2, simplify to find your answer: the expression evaluates to 12.
