Question

A student is trying to solve the system of two equations given below:

Equation P: y + z = 6
Equation Q: 3y + 4z = 1

Which of the following is a possible step used in eliminating the y-term? (1 point)


(y + z = 6) • 4

(3y + 4z = 1) • 4

(y + z = 6) • –3

(3y + 4z = 1) • 3

Answer 1

if you are going to eliminate the y term the y must be the same value but different signs

since the second equation has y, a value of 3 you mist make the first one -3 so you will multiply the whole equation by -3
c is the answer
