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.0to eliminate y, you have to multiply by a non zero number so that your new y, if added to the y in the other equation, the result will be zero. so in this case, only 5y + 5y will eliminate y. so the answer is B.
