1 answer:

5 0

If you would like to simplify Q + S - T, you can do this using the following steps:<span>

Q = 7m + 3n,
R = 11 - 2m,
S = n + 5,
T = -m - 3n + 8

</span>Q + S - T = 7m + 3n + n + 5 - (-m - 3n + 8) = 7m + 3n + n + 5 + m + 3n - 8 = 8m + 7n - 3

The correct result would be <span>8m + 7n - 3.</span>
