Answer:
(i) 8y - 5x - 7xy - 2ab
(ii) 11pqr - 5mr - 1 + 9s
(iii) 29ac - 40 + 14y +12abc
Step-by-step explanation:
(i) 2x + 3y - 7xy + 9ab - 7x + 5y - 11ab
= 2x - 7x + 3y + 5y - 7xy + 9ab - 11ab
= -5x + 8y - 7xy - 2ab
(ii) -5pqr + 7mr - 4 - 2s + 3 + 11s - 4mr + 6qpr - 12rm + 10rpq
= -5pqr + 6pqr (qpr and par are same) + 10pqr + 7mr - 12mr - 4 + 3 - 2s + 11s
= 11pqr - 5mr - 1 + 9s
(iii) 4ac - 23 + 11y - 6ac + 4y - 17 + ac - y + 31ca + 12abc - ca
= 4ac - 6ac + ac - ac + 31ac - 23 - 17 + 11y + 4y - y + 12abc
= 29ac - 40 + 14y + 12abc
Hope this helps. Oh and Merry Christmas!
