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? (4 points)


−1(4a + 2b = 19)

−4(4a + 2b = 19)

−4(a + b = 6)

4(a + b = 6)

Your answer is the third one. WHen it comes to system of equations, this will cancel out 4a, therefore isolating the variable. That turns the equation into -2b=-5.
