Question

How many solutions does the following system of equations have?

{y=x72
{Y = -x + 2

one solution
no solutions
two solutions
infinitely many solutions

Answer 1

This system has one solution only

Explanation:

We have to evaluate the equations shown in the picture you gave

Since the equations differs, they are not the same, this system has only on solution for x and for y.

In fact, if we sum them, we obtain y=0, and then x=2
