Question

What is the value of n in the equation (n – 4) – 3 = 3 – (2n + 3)? n =

Answer 1

n =
`(7)/(3)`.

Explanation:

Given : (n – 4) – 3 = 3 – (2n + 3).

To find : What is the value of n in the equation.

Solution : We have given

(n – 4) – 3 = 3 – (2n + 3).

Remove parenthesis

n – 4 – 3 = 3 – 2n - 3.

Combining like terms

n - 7 = 3 - 2n - 3.

n - 7 = - 2n.

On adding both sides by 2n

n + 2n - 7 = 0.

3n -7 = 0 .

On adding both sides by 7

3n = 7 .

On dividing by 3 both sides

n =
`(7)/(3)`.

Therefore, n =
`(7)/(3)`.

Answer 2

Answer
n = 7/3


Explanation
(n-4)-3=3-(2n+3)
Open the parenthesis first
n-4-3=3-2n-3
n-7=-2n
n+2n = 7
3n = 7
n = 7/3
