Plz 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 y-term? (y + z = 6) ⋅ 9 (y + z = 6) ⋅ −5 (5y + 9z = 1) ⋅ 9 (5y + 9z = 1) ⋅ 5

The two equations are

P: y+z =6 and

Q: 5y +9z =1

Now to eliminate y , we have to make the coefficient of y same and with opposite sign

In equation Q , the coefficient of y is 5

So in equation P the coefficient of y should be -5

So we multiply equation P by -5

So (y + z = 6) ⋅ −5

Option second is correct
