Answer:
Option C is correct
(y + z = 6) ⋅ −3
Step-by-step explanation:
As per the statement:
A student is trying to solve the system of two equations given below:
Equation P: y + z = 6 ....[1]
Equation Q: 3y + 4z = 1 ....[2]
Multiply the equation [1] by -3 to both sides we have;
[tex]-3 \cdot (y+z = 6)[/tex]
or
[tex]-3y -3z = -18[/tex] ......[3]
Add equation [2] and [3] to eliminate the y-term;
[tex]z = -17[/tex]
or
z = -17
Therefore, the possible step used in eliminating the y-term is, (y + z = 6) ⋅ −3
