The answer to your question would be A.
Answer:
A. x=5,y=6
Step-by-step explanation:
Add y to both sides of the equation.
x=−1+y
x−3y=−13
Replace all occurrences of x with −1+y in each equation.
−1−2y=−13
x=−1+y
Solve for y in the first equation.
y=6
x=−1+y
Replace all occurrences of y with 6 in each equation.
x=5
y=6
The solution to the system is the complete set of ordered pairs that are valid solutions.
(5,6)
The result can be shown in multiple forms. Equation Form: x=5,y=6
