Question

-3.6 = -\frac{a}{0.8} - 1.6

Explanation:

Step1: Isolate the fraction term

Add 1.6 to both sides.
$$-3.6 + 1.6 = -\frac{a}{0.8}$$
$$-2 = -\frac{a}{0.8}$$

Step2: Eliminate the negative sign

Multiply both sides by -1.
$$2 = \frac{a}{0.8}$$

Step3: Solve for $a$

Multiply both sides by 0.8.
$$a = 2 \times 0.8$$

Answer:

$a = 1.6$
