Pomocy. Mam problem z zadaniem domowym. Na jutro :)

Zad: 8 3p + 4p + 2 = 2p + p + 3p + p + 2 = 7p + 2 9z - 4z + z = 5z + 4z - 3z - z + z = 5z + z 6m + 2w - m - w = 4m + 2m + w + w - m - w = 5m + 2w - w b + d + b + 2d = b + d + b + d + d = 2b + d + 2d Zad: 9 7w + 9w = 16w s + s + 2 = 2s + 2 2x + 3p + x + p = 3x + 4p 15z - 9z = 6z 5k + 7m - 4k - 7m = k
