What is the solution of the system x − 3y = –13 and 5x + 7y = 34? a. `x = (6)/(5)`, y = 4 b. `x = (7)/(2), y = (9)/(2)` c. `x = (1)/(2), y = (9)/(2)` d. x = –3, y = 7

For this case we have the following system of equations:

From the first equation we clear "x":

We substitute in the second equation:

We apply distributive property:

We add similar terms:

We add 65 to both sides:

We divide between 22 on both sides:

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

Thus, the solution of the system is:
