A particular shade of orange paint has 2 cups of yellow paint for every 3 cups of red paint. According to the double number line, how many cups of red paint are required to make three batches

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 =
