I'm attempting to do these problems but I can't seem to get them down.​

1-for what value of x is line a parallel to line b 2-for what value of x is line a parallel to line b

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 =

Need on this geometry question. explain how you did it.
