Your teacher is giving you a test worth 100 points containing 40 questions. there are 2 point and 4 point questions on the test. how many of each type of questions are on the test. use a system of linear equations to solve .

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 =
