A nurse is performing a pre-assessment before a patient is seen by a physician. The patient’s weight is inaccurate due to the calibration of the scale.
The patient’s temperature changes during the pre-assessment.
The nurse measures the patient’s weight twice and observes two different measurements.
The nurse estimates the patient’s weight based on the increments on the scale.

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14
