ANSWER

No solution

Step-by-step explanation

The first equation is

$y = {x}^(2) - 2x$

and the second equation is

y = - 2x - 1

We equate the two equations to obtain;

${x}^(2) - 2x = - 2x - 1$

This implies that

${x}^(2) = - 2x + 2x - 1$

${x}^(2) = - 1$

There is no real number whose square is -1.

Therefore, the equation has no solution.
