The Answer of Use Back-Substitution to Solve the Triangular System$$\left\{ \begin{aligned}
x + y - z & = - 5 \
y - z & = 5 \
\frac { 1 } { 3 } z & = - \frac { 4 } { 3 }
\end{aligned} \right.$$

Use Back-Substitution to Solve the Triangular System $\left\{ \begin{aligned}x + y - z & = - 5 \\y - z & = 5 \\\frac { 1 } { 3 } z & = - \frac { 4 } { 3 }\end{aligned} \right.$
