Give brainliest answers given: q = 7m + 3n, r = 11 - 2m, s = n + 5, and t = -m - 3n + 8. simplify [q - r] + [s - t]. 10m + 5n - 24 10m - 5n + 24 10m + 7n - 14 10m - 7n - 14

Let's simplify one part at a time.q - r = 7m + 3n - (11 - 2m)q - r = 7m + 3n - 11 + 2mq - r = 9m + 3n - 11we now do s - t.s - t = n + 5 - (-m - 3n + 8)s - t = n + 5 + m + 3n - 8s - t = 4n + m - 3put it all together.[q - r] + [s - t] = 9m + 3n - 11 + 4n + m - 3answer: 10m + 7n - 14

Im pretty sure it is a
