Question

a number subtracted from 16 is -3.

Explanation:

Step1: Define the variable

Let the number be \( x \). The phrase "a number subtracted from 16" translates to \( 16 - x \).

Step2: Set up the equation

We know that this result is \(-3\), so the equation is \( 16 - x = -3 \).

Step3: Solve for \( x \)

Subtract 16 from both sides: \( -x = -3 - 16 \), which simplifies to \( -x = -19 \). Multiply both sides by \(-1\) to get \( x = 19 \).

Answer:

The number is \( \boldsymbol{19} \)
