Find the value of $d$ where $d$ increased by 4 is -1.

STEP 1

Assumptions
1. Let $d$ represent the unknown number.
2. The phrase "increased by four" means we add 4 to $d$ .
3. The phrase "is negative one" means the result of increasing $d$ by four is equal to -1.

STEP 2

Translate the given verbal statement into an algebraic equation. The statement "A number, $d$ , increased by four is negative one" can be written as:
$d + 4 = -1$

STEP 3

To find the value of $d$ , we need to isolate $d$ on one side of the equation. We can do this by subtracting 4 from both sides of the equation.
$d + 4 - 4 = -1 - 4$

STEP 4

Simplify both sides of the equation.
$d = -1 - 4$

STEP 5

Calculate the value on the right side of the equation.
$d = -5$
The value of $d$ is -5, which corresponds to option C.
