I literally have a masters in mathematics and the ONLY correct answer is 1. You can rewrite the equation multiple ways to clarify. In PEMDAS, "m" is before "d" for a reason, and that reason is the distributive property. You would never, NEVER divide first because it removes the distribution from the paranthetical component of the equation. As an example, solve for X and you could never initiate by dividing both sides by 4 because it is literally attached to the parenthesis.

This equation floats around on social media by social engineers who want idiotic people to argue over this until everyone throws their hands up in the air and gives up, or resigns themselves to uncertainty. This is essentially a common core poll, to get an idea of what percentage of the population are fucking morons, but worse... opinionated morons even though they know themwelves that they're not specialists and were probably shit at math.

Shut your fucking mouth, please.
