Question

Solve the equation :

3 (n - 5 ) = - 21

so n = ?

Answer 1

Answer:

n= -2

Explanation:

3(n - 5) = -21

3n-15=-21

3n=-21+15

3n=-6

n=-6/3

n=-2

Answer 2

Answer:

=> The value of n is -2.

Explanation:

Given that: -

$3(n -5)=-21$

As we have to determine the value of n,

For that, we have to apply the rule of DMAS:

As we have:

=> $3(n -5)=-21$

Multiply $3$ with the bracket term,

=> 3n - 15 = -21

Add both the sides by $15$, we get

=> 3n - 15 + 15 = -21 + 15

Simplifying it further we get,

=> 3n = -6

Now, divide both the sides by $3$, we get

=> n = -2

Hence, the value of n is -2.
