Question

12+(n-1)×6=96 find the value of n

Answer 1

Answer:

n=5

Step-by-step explanation:

12+(n-1)×6=96

12+(n-1)=96÷6

12+(n-1)=16

n-1=16-12

n-1=4

n=4+1

n=5

Answer 2

Answer:

The value of n is 15.

Step-by-step-explanation:

12 + ( n - 1 ) × 6 = 96

⇒ 12 + 6n - 6 = 96

⇒ 12 - 6 + 6n = 96

⇒ 6 + 6n = 96

⇒ 6n = 96 - 6

⇒ 6n = 90

⇒ n = 90 / 6

⛬ n = 15

To check the correctness of answer :

Put the value of 'n' which is 15 in the given equation.

The R. H. S. of the given equation is 96.

If L. H. S. will be 96, then the answer is correct.

∴ L. H. S. = 12 + ( n - 1 ) × 6

⇒ 12 + ( 15 - 1 ) × 6 ....( By putting the value of n )

⇒ 12 + ( 14 ) × 6

⇒ 12 + 14 × 6

⇒ 12 + 84 ... ( By BODMAS rule we multiply first. )

∴ L. H. S = 96

⛬ L. H. S. = R. H. S.

The value of n is 15.
