Answer:
17n-25m
Step-by-step explanation:
m - 5n - 2 [5m - {2n -3 (m - 2n) - (5m - 3n)}]
= m - 5n - 2 [5m - {2n -3m +6n - (5m - 3n)}]
=m - 5n - 2 [5m - {2n -3m +6n - 5m +3n}]
=m - 5n - 2 [5m - 2n +3m -6n + 5m -3n]
= m- 5n - 10m + 4n -6m + 12n - 10m + 6n]
= m(1-10-6-10) +n(4-5+12+6)
=m×-25 + n× 17
=17n-25m
