Question

Evaluate the expression: 16-3n when n=-4

Answer 1

ANSWER

28

EXPLANATION

To evaluate the expression, we have to substitute n with -4,

$16-3(-4)$

Solve the product,

$16-3(-4)=16-(-12)$

And add. Remember that the minus sign changes the sign in the parenthesis - i.e. it is 16 plus 12,

$16-(-12)=16+12=28$

Hence, the value of the given expression when n = -4 is 28.
