Question

If (2n + 5) = 3 (3n – 10), then the value of n is​

Answer 1

(2n + 5) = 3(3n - 10)

(2n + 5) = 9n - 30

2n - 9n = 30 - 5

-7n = -35

n = -35/7

n = -5

Therefore the value of n is -5

Hope it helps :)

Answer 2

Answer:

(2n + 5) = 3 (3n – 10)

2n+5=9n−30

2n+5−9n=9n−30−9n

−7n+5=−30

−7n+5−5=−30−5

−7n=−35

n=5

Explanation:

First, open the bracket. Then subtract 9n from both sides. Then subtract 5 from both sides and finally divide both sides by -7 and you will get the answer.
