B O 6(3s + 7) and 9s + 13
D 42 +212 and 7(6 + 3z)
F 2(b + 3c) + 5 and 2b + 6c + 10

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 =
