Question

3m-2m+5m 5n-3+n+6 5pq+k-7pq-k 4a-5b+5b+4a

Answer 1

4m-2m+5m=7m
5n-3+n+6=6n+3
5pq+k-7pq-k=-2pq
4a-5b+5b+4a=8a

Answer 2

Simplifying each of the expressions:

• 3m - 2m + 5m = 6m (combine like terms)
• 5n - 3 + n + 6 = 6n + 3 (combine like terms and simplify)
• 5pq + k - 7pq - k = -2pq (combine like terms and simplify)
• 4a - 5b + 5b + 4a = 8a - 5b (combine like terms)

Therefore:

• 3m - 2m + 5m = 6m
• 5n - 3 + n + 6 = 6n + 3
• 5pq + k - 7pq - k = -2pq
• 4a - 5b + 5b + 4a = 8a - 5b
