Which ordered pair is the best estimate for the solution of the system of equations? y=−2/5x−2y=5x+1
lutik1710 [3]

Option a: (-0.5,-1.75) is the solution to the system of equations.

Explanation:

The equations are y=-\frac{2}{5} x-2 and y=5 x+1

Equating these two equations, we have,

-\frac{2}{5} x-2=5 x+1

Taking LCM and multiplying both sides by 5, we get,

-2 x-10=25 x+5

Simplifying , we get,

\begin{aligned}-10-5 &=25 x+2 \\-15 &=27 x \\-\frac{15}{27} &=x \\-\frac{5}{9}  &=x\end{aligned}

Substituting the value of x in y=5 x+1, we get,

\begin{aligned}&y=5\left(-\frac{5}{9}\right)+1\\&y=-\frac{25}{9}+1\\&y=-\frac{16}{9}\end{aligned}

Thus, the solution is \left(-\frac{5}{9},-\frac{16}{9}\right)

Changing the solution from fraction to decimal, we get, (-0.556,-1.778)

Thus, the solution is (-0.5,-1.75)

Hence, option a is the correct answer.
