x= 5 x z= 3 = 15 (4y - 2z) = 60 - -30 = 30 so its C
For this case we must solve the following system of equations:

To solve we follow the steps below:
We multiply the second equation by -3:

Thus, we have the equivalent system:

We add the equations:

We look for the value of the variable "y":

Thus, the solution of the system is given by:
