The evaluated expression is \( 2 \).
Answer for screen readers
The final answer is ( 2 ).
Steps to Solve
- Substitute the value of b Substituting ( b = -3 ) into the expression ( 14 + 4b ) gives us:
$$ 14 + 4(-3) $$
- Calculate the multiplication Next, calculate ( 4 \times -3 ):
$$ 4 \times -3 = -12 $$
- Add the result to 14 Now, substitute the result back into the expression:
$$ 14 - 12 $$
- Perform the addition Finally, calculate ( 14 - 12 ):
$$ 14 - 12 = 2 $$
The final answer is ( 2 ).
More Information
When evaluating expressions, substituting the variable with its corresponding value is fundamental. This straightforward operation illustrates how negative values affect an expression and reinforces the concept of basic arithmetic.
Tips
- Failing to distribute the negative sign: Ensure that multiplication with negative numbers is done carefully.
- Forgetting to perform each step sequentially: It's important to follow the order of operations correctly.
