Which step could be used to help isolate the variable in the following equation?5.6j – 0.12 = 4 + 1.1j

Subtracting 1.1j from both sides combines the variable terms on one side: 5.6j − 1.1j − 0.12 = 4, or 4.5j − 0.12 = 4. This is a useful step toward isolating j. The other choices do not move a variable term from one side to the other.
