= 15i + 14b + 13k - 30i - 45j + 51k
= 15i - 30i + 14b + 13k + 51k - 45j
= -15i + 14b + 64k - 45j
2. (42n + 35m + 7) - (50m - 20n + 9)
= 42n + 35m + 7 - 50m + 20n - 9
= 42n + 20n + 35m - 50m + 7 - 9
= 62n - 15m - 2
3. (4y - 8) - (2y + 15z)
= 4y - 8 - 2y - 15z
= 4y - 2y - 8 - 15z
= 2y - 8 - 15z
4. (6x + 4) - (x - y)
= 6x + 4 - x + y
= 6x - x + 4 + y
= 5x + 4 + y
