Astudent 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?
a (y + z = 6) ⋅ −8
b(y + z = 6) ⋅ 7
c (8y + 7z = 1) ⋅ 7
d (8y + 7z = 1) ⋅ 8

If you would like to know what is a possible step used in eliminating the y-term, you can calculate this using the following steps:

y + z = 6          /*(-8)
8y + 7z = 1


-8 * (y + z) = -8 * 6
8y + 7z = 1


-8y - 8z = -48
8y + 7z = 1

7z - 8z = 1 - 48

The correct result would be a) (y + z = 6) * (-8).

Where's the rest of the
