Question

solve for j.\
-12j + 6j + 18 = -20 - 4j\
j = \boxed{}

Explanation:

Step1: Combine like terms on left

$-12j + 6j = -6j$, so equation becomes $-6j + 18 = -20 - 4j$

Step2: Add 4j to both sides

$-6j + 4j + 18 = -20$, simplifies to $-2j + 18 = -20$

Step3: Subtract 18 from both sides

$-2j = -20 - 18$, so $-2j = -38$

Step4: Divide by -2

$j = \frac{-38}{-2} = 19$

Answer:

19
