Hello! I really don't understand these soft of equations so could you be kind and help me figure how to slove these types of questions with this as an example? thanks!

Complete the equation of the line through (−10,3) and (−8,−8). use exact numbers.

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 =
