Question

What is the value of n? n − 2 = 1/2 (10n + 4)

Answer 1

The value of n is -1

Given:

`n-2=(1)/(2)(10n+4)`

Explanation:

In this problem, we need to find the value of 'n'.

The 'n' is the variable whose value changes with respect to the set of conditions. The value of the variable changes every time and it can symbol or a letter.

To solve this problem, we need to bring the variables on one side and constants on another side.

The value of constants remains same.

`\Rightarrow 2(n-2)=10 n+4`

`\Rightarrow 2 n-4=10 n+4`

`\Rightarrow-4-4=10 n-2 n`

`\Rightarrow-8=8 n`

`\Rightarrow n=-(8)/(8)`

`\therefore n=-1`

Answer 2

n = -1

Explanation:

n - 2 = 1/2 (10n+4) // We have the equation.

n - 2 = 5n + 2 // Solve the righ side.

n - 5n = 2 + 2 // Group common terms.

-4n = 4 // Solve.

n = -4/4

n = -1
