The solution to the system of equations is
\(x = 2\) and
\(y = -3\).

To find the solution of the system of equations, you can use the method of elimination. Add the two equations to eliminate the \(y\)-terms:


\[ (2x + 5y) + (-8x - 5y) = -11 + (-1) \]

Combine like terms:


\[ -6x = -12 \]

Now, solve for \(x\):


\[ x = (-12)/(-6) = 2 \]

Now that you have the value of \(x\), substitute it back into one of the original equations to solve for \(y\). Let's use the first equation:


\[ 2x + 5y = -11 \]


\[ 2(2) + 5y = -11 \]


\[ 4 + 5y = -11 \]

Subtract 4 from both sides:


\[ 5y = -15 \]

Divide by 5:


\[ y = -3 \]

So, the solution to the system of equations is
\(x = 2\) and
\(y = -3\).
