Can any one me with the answers to these questions asap?

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 =

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4
