Sagot :
To solve the given system of equations:
[tex]\[ \left\{ \begin{array}{c} y = x + 11 \\ -y = -x + 11 \end{array} \right. \][/tex]
Let's simplify the second equation to make it more comparable to the first. Simplifying [tex]\(-y = -x + 11\)[/tex] results in:
[tex]\[ y = x - 11 \][/tex]
Now we have the following system of equations:
[tex]\[ \left\{ \begin{array}{c} y = x + 11 \\ y = x - 11 \end{array} \right. \][/tex]
To find the solution, we set the right-hand sides of the equations equal to each other:
[tex]\[ x + 11 = x - 11 \][/tex]
Subtracting [tex]\(x\)[/tex] from both sides, we get:
[tex]\[ 11 = -11 \][/tex]
This statement is a contradiction and is never true. This means there is no value of [tex]\(x\)[/tex] that can satisfy both equations simultaneously.
Therefore, there is no solution to this system of equations. The correct answer is:
no solution
