A student is trying to solve the system of two equations given below: Equation P: a + b = 6 Equation Q: 4a + 2b = 19 Which of the following steps can be used to eliminate the a term? −1(4a + 2b = 19)

−4(4a + 2b = 19)

−4(a + b = 6)

4(a + b = 6)

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2
