Question 10 • Algebra I

Which step could be used to help isolate the variable in the following equation? 5 point 6 j minus 0 point 1 2 is equal to 4 plus 1 point 1 j

Answer
A
Subtract 4 j from both sides.
B
Subtract 0 point 1 2 from both sides.
C
Subtract 1 point 1 j from both sides.
D
Subtract 5 point 6 from both sides.

Explanation

The equation is 5.6j − 0.12 = 4 + 1.1j. To collect the variable terms on one side, subtract 1.1j from both sides; this removes the 1.1j term on the right while keeping the equation balanced. Then you can continue isolating j. The correct choice is “Subtract 1.1j from both sides.”
