Which statements are true when using algebra tiles to solve the equation 8x + (–4) = 11x + 5? Check all that apply.

Add 8 negative x-tiles to each side; the 8 positive x-tiles on the left pair with them to make zero, so A is true. Then add 5 negative unit tiles to each side to cancel the 5 positive units on the right, making D true. This leaves −9 = 3x, so divide both sides by 3 to get x = −3; E is true and F is false.
