which step could be used to help isolate the variable in the following equation? 5.6j - 0.12 = 4 + 1.1j\nsubtract 0.12 from both sides.\nsubtract 5.6 from both sides.\nsubtract 4j from both sides.\nsubtract 1.1j from both sides.

Answer

Explanation:

Step1: Analyze goal of isolating variable

To isolate the variable $j$ in the equation $5.6j - 0.12=4 + 1.1j$, we want to get all terms with $j$ on one - side.

Step2: Consider operation on $j$ terms

Subtracting $1.1j$ from both sides will move the $j$ terms to the left - hand side. If we subtract $1.1j$ from both sides, the left - hand side becomes $5.6j-1.1j - 0.12=(5.6 - 1.1)j-0.12 = 4.5j-0.12$, and the right - hand side becomes $4+1.1j - 1.1j=4$.

Answer:

Subtract 1.1j from both sides.
