Question

solve for d.
19.74 < 1 - d

Explanation:

Step1: Subtract 1 from both sides

To isolate the term with \( d \), we subtract 1 from both sides of the inequality \( 19.74 < 1 - d \). This gives us \( 19.74 - 1 < -d \), which simplifies to \( 18.74 < -d \).

Step2: Multiply both sides by -1 (and reverse inequality)

When we multiply or divide both sides of an inequality by a negative number, we must reverse the inequality sign. Multiplying both sides of \( 18.74 < -d \) by -1 gives \( -18.74 > d \), or equivalently \( d < -18.74 \).

Answer:

\( d < -18.74 \)
