Write a corresponding real world problem to represent 2x - 125=400

12x + 1 = 25 solve the following equation. then place the correct number in the box provided.

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 =
