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

Equation P: y + z = 6
Equation Q: 8y + 7z = 1

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


(y + z = 6) • –8

(y + z = 6) • 7

(8y + 7z = 1) • 7

(8y + 7z = 1) • 8

Answer 1

(y + z = 6) • –8

Explanation:

Because in order to eliminate 8 you will need to multiply by a negative number so that you can eliminate a positive number.

Hope this helped!

Answer 2

(y + z = 6) * -8 <====
