Even though it was not easy, and they needed multiple tries and expeditions to manage to settle in the new environment, they managed it at the end and became the first humans in the New World.

for this case we have the following equation:

we apply distributive property to the terms within parentheses.

subtracting 2 on both sides of the equation:
