Question

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

Answer 1

Answer:

The value of 2n - 2 is 4.

Step-by-step 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.
