Answer:
x∈{-7√2, 7√2}
Step-by-step explanation:

Distributive property: 5y-3y-6
Combine like terms: 2y-6
So there's your answer
The best approximation for the solution to this system of equations is (-2.2,-3)
Option C is correct.
Step-by-step explanation:
Solving the system of equations to get the exact value of x:

Let

Putting value of y from eq(1) into eq(2)



So, Value of x is -2.2
The best approximation for the solution to this system of equations is:
x=-2.2 and y = -3
(-2.2,-3)
Option C is correct.
