Answer: j = -0.45

Explanation:

Step 1: Combine like terms

2.25 - 11j - 7.75 + 1.5j = 0.5j - 1

-5.5 - 9.5j = 0.5j - 1

Step 2: isolate your variable

-5.5 - 9.5j = 0.5j - 1

Subtract 0.5j from both sides

-5.5 - 10j = -1

Add 5.5 to both sides

-10j = 4.5

Divide both sides by -10

j = -0.45

Answer:


j = - 0.45

Explanation:

Combine like terms and apply the rules of algebra.


2.25 - 11j - 7.75 + 1.5j = 0.5j - 1


- 5.5 - 9.5j = 0.5j - 1


- 9.5j = 0.5j + 4.5


- 10 j= 4.5


j = - 0.45
