Answer:
Step-by-step explanation:
2a.x=10+5
b. x=11-7
C. x=5*2
For this case we have the following system of equations:

To solve, we clear "x" from the second equation:

We substitute "x" in the first equation:

We clear the value of the variable "y":

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

Thus, the solution of the system is given by:
