29.(08.05 LC) 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 these is a possible step used in eliminating the y-term? (1 point)
O (y + 2 = 6).9
O (y + 2 = 6). - 5
(5y + 9 = 1) - 9
5y + 92 = 1) 5

Answer this question only if you know the 30 points and
