Fredrick designed an experiment in which he spun a spinner 20 times and recorded the results of each spin

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 =

Me d is also an option but i couldn't get it in the picture
