In the equation 2X + 6 = 2(X + 3), what happens after applying the distributive property?

• 2X + 6 = 2X + 3

• 2X + 6 = 2X - 6

• 2X + 6 = 2X + 6

• 2X + 6 = X + 6

What does it mean if an equation simplifies to 6 = 6?

• The equation is incorrect

• There are no solutions

• There is one solution

• There are infinite solutions

In the equation X + 3 = X - 5, what happens when you subtract X from both sides?

• 3 = -5

• X = -5

• 3 = X

• X = 3
