Question

If n + 7 = 10, evaluate 2n - 2
O 3
0 17
4
6

Answer 1

The value of 2n - 2 is 4.

Explanation:

Given the equation

`n + 7 = 10`

Subtract 7 from both sides of the equation

`n+7-7=10-7`

Simplify

`n=3`

Now substituting n = 3 in the equation

2n - 2 = 2(3) - 2

= 6 - 2

= 4

Therefore, the value of 2n - 2 is 4.
