∠e and ∠ f are the remote interior angles of ∠ p and the remote interior angles of ∠ q and the remote interior angles of ∠ r

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
