Part D - Isolating a Variable with a Coefficient In some cases, neither of the two equations in the system will contain a variable with a coefficient of 1, so we must take a further step to isolate it. Let's say we now have • 3C + 4D = 5 • 2C + 5D = 2 None of these terms has a coefficient of 1. Instead, we'll pick the variable with the smallest coefficient and isolate it. Move the term with the lowest coefficient so that it's alone on one side of its equation, then divide by the coefficient. Which of the following expressions would result from that process? C =} - D C =1-D D=-C %3D - }C D = Submit Previous Answers Correct

Transcribed Image Text:Part D - Isolating a Variable with a Coefficient
In some cases, neither of the two equations in the system will contain a variable with a coefficient of 1, so we must take a
further step to isolate it. Let's say we now have
3C + 4D = 5
• 20 + 5D = 2
None of these terms has a coefficient of 1. Instead, we'll pick the variable with the smallest coefficient and isolate it. Move
the term with the lowest coefficient so that it's alone on one side of its equation, then divide by the coefficient. Which of the
following expressions would result from that process?
O C=} - D
