Question

Find the value of n. 2 x 120 = (4 x n) + (4 x 20)

Answer 1

• 40

Task :

• To work out the value of n

Solution :

`\rightarrow \: 2 * 120 = (4 * n) + (4 * 20)`

`\rightarrow \: 240 =4n \: + 80`

`\rightarrow \: 240 - 80=4n \: + 80 \: - 80`

`\rightarrow \: 16 0 =4n`

`\rightarrow \: (160)/(4) = (4n)/(4) \\`

`\rightarrow \: \: n = 40`

Therefore,the value of n = 40.

Answer 2

n = 40

Explanation:

To find the value of n, we can solve the equation:

`\sf 2 * 120 = (4 * n) + (4 * 20)`

Simplifying the both sides of the equation, we get:

240 = 4n + 80

Subtracting 80 from both sides of the equation, we get:

240 - 80 = 4n + 80 - 80

160 = 4n

Dividing both sides of the equation by 4, we get:

`\sf (160)/(4)=(4n)/(4)`

40 = n

Therefore, the value of n is 40.
