Question

d) d·88 = -88,000

Explanation:

Step1: Isolate the variable \( d \)

To solve for \( d \) in the equation \( d \cdot 88 = -88000 \), we divide both sides of the equation by 88. This is based on the division property of equality, which states that if \( a = b \), then \( \frac{a}{c}=\frac{b}{c} \) (where \( c
eq0 \)). So we have:

$$ \frac{d \cdot 88}{88}=\frac{-88000}{88} $$

Step2: Simplify both sides

Simplifying the left - hand side, \( \frac{d\cdot88}{88}=d \) (because a non - zero number divided by itself is 1, and \( d\times1 = d \)). For the right - hand side, we calculate \( \frac{-88000}{88}=- 1000 \) (since \( 88\times1000 = 88000 \), and a negative number divided by a positive number gives a negative result).

Answer:

\( d=-1000 \)
