Evaluate the expression 2n - 6 if n = 16.
V125BC [204]

Answer:

26

Step-by-step explanation:

2n-6

Given that:

n=16

To evaluate the expression, we must simply substitute the given value of n, which is 16, for n:

2(16)-6

Multiply:

32-6

Subtract:

26

-

To check your work, simply set the given expression equal to our solution, 26:

2n-6=26

Add 6 to both sides of the equation:

2n=32

Divide both sides of the equation by the coefficient of n, which is 2:

n=16

Since it matches the given value of n, our solution is correct!
