Question

value of n in 3(n-5)=-21​

Answer 1

Answer:

2

Step-by-step explanation:

3(n-5)=21

n-5=21/3

n-5=7

n=7-5

n=2

Answer 2

3(n - 5) = 21

or, 3n - 15 = 21

or, 3n = 21 + 15

or, 3n = 36

or, n = 36/3

or, n = 12

Hence, n = 12.

Verify-

3(12 - 5) = 21

or, 3 × 7 = 21

or, 21 = 21

Hence, L.H.S = R.H.S
