Answer:

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

$x=5,\:y=-1$

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:

$x=5,\:y=-1$
