Question

5.6j-0.12 = 4+1.1j which step could be used to help isolate the variable

Answer 1

j = 206/225  

Step-by-step explanation:

5.6j-0.12 = 4+1.1j

Step 1 :

Add 0.12 both sides

=> 5.6j -0.12 + 0.12 = 4 + 1.1j + 0.12

=> 5.6j  = 4.12 + 1.1j

Step 2:

Subtract 1.1j from bith sides

=> 5.6j - 1.1j = 4.12 + 1.1j - 1.1j

=> 4.5 j  = 4.12

Step 3 :

Dividing by 4.5 from both sides

=> 4.5 j / 4.5  = 4.12 / 4.5

=> j = 412/450

=> j = 206/225
