Answer:
(-2.2,-3)
Step-by-step explanation:
We have been given a system of equations and we are asked to find the best approximation for the solution to this system of equations.
\(y=-3...(1)\)
\(y=x-0.8...(2)\)
We will use substitution method to solve for the system of equations.
Upon substituting equation (1) in equation (2) we will get,
\(x-0.8=-3\)
Upon adding 0.8 to both sides of our equation we will get,
\(x-0.8+0.8=-3+0.8\)
\(x=-2.2\)
Therefore, the best approximate value of x is -2.2 and approximate value of y is -3.
