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

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

Answer

Explanation:

Step1: Recall equation - solving goal

To isolate the variable $j$, we want to get all terms with $j$ on one - side.

Step2: Analyze each option

Subtracting 0.12 from both sides will not help in isolating $j$. Subtracting 5.6 from both sides is incorrect as we don't want to get rid of the coefficient of $j$ in that way. Subtracting $4j$ from both sides is wrong as there is no $4j$ term in the original equation. Subtracting $1.1j$ from both sides will move the $j$ terms to one side: [5.6j-0.12-(1.1j)=4 + 1.1j-(1.1j)] [5.6j-1.1j-0.12=4] [4.5j-0.12 = 4]

Answer:

Subtract 1.1j from both sides.
