A student is trying to solve the system of two equations given below:
Equation P: y + z = 6
Equation Q: 5y + 9z = 1
Which of the following is a possible step used in eliminating the yterm?
(y + z = 6) ⋅ 9
(y + z = 6) ⋅ −5
(5y + 9z = 1) ⋅ 9
(5y + 9z = 1) ⋅ 5

Best ResponseYou've already chosen the best response.1You want to eliminate y terms, so you would want coefficient of y to be same, so you can just subtract equations there, right?

Best ResponseYou've already chosen the best response.1So for first equation, coefficient of y is 1. In second equation, it is 5. So you want to multiply first equation by 5 so you can subtract. (Or 5 then add)
