Answer:

Therefore, the solution of the system of equations will be:

x=5,\:y=-1

Step-by-step explanation:

Given the system of equations

x-y=6;\:y=-1

solving

\begin{bmatrix}x-y=6\\ y=-1\end{bmatrix}

\mathrm{Subsititute\:}y=-1

\begin{bmatrix}x-\left(-1\right)=6\end{bmatrix}

\begin{bmatrix}x+1=6\end{bmatrix}

Isolate x for x+1=6

x+1=6

x=5

Therefore, the solution of the system of equations will be:

x=5,\:y=-1
