solve the following equation:
$-15 - \frac{1}{4}j = 10$
skill code: 82080

Explanation:

Step1: Isolate the variable term

Add 15 to both sides.
$$-15 - \frac{1}{4}j + 15 = 10 + 15$$
$$-\frac{1}{4}j = 25$$

Step2: Solve for $j$

Multiply both sides by -4.
$$-\frac{1}{4}j \times (-4) = 25 \times (-4)$$

Answer:

$j = -100$
