Answer:
(-3,-5) because the point satisfies both equations.
Explanation:
We are given that two lines A and B
Line A:

Line B:

We have to find the solution of the given system of equation and explain .
Using elimination method
Eliminate y by subtracting equation first from equation second then, we get



Substitute x=-3 in equation first

Hence, the solution of given system of equation is (-3,-5).
Substitute x=-3 and y=-5 in first equation then , we get

LHS=RHS
Hence, (-3,-5) satisfies the the equation.
Substitute x=-3 and y=-5 in second equation
Then, we get

LHS=RHS
Hence, (-3,-5) satisfies the equation.
Hence, (-3,-5) is the solution of the system of equations because the point satisfies both equations.
Answer:(-3,-5) because the point satisfies both equations.
