Which expression is equivalent to 8(k + m) − 15(2k + 5m)?

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 =

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much
