Question

. 3pq + 7, -5pq +8, 8pq - 9 add the following algebraic expressions​

Answer 1

Answer:

6 p q + 6

Step-by-step explanation:

Simplify the following:

3 p q + 7 - 5 p q + 8 - 9 + 8 p q

Grouping like terms, 3 p q + 7 - 5 p q + 8 - 9 + 8 p q = (8 p q + 3 p q - 5 p q) + (7 + 8 - 9):

(8 p q + 3 p q - 5 p q) + (7 + 8 - 9)

p q 8 + p q 3 + p q (-5) = 6 p q:

6 p q + (7 + 8 - 9)

7 + 8 = 15:

6 p q + 15 - 9

15 - 9 = 6:

6 p q + 6

Factor 6 out of 6 p q + 6:
