Rewrite the System of Inequalities, Adding Slack Variables or Subtracting $\mathrm{x}_{1}+\mathrm{x}_{2}+\mathrm{x}_{3}+\mathrm{s}_{2}=23$

Multiple Choice

Rewrite the system of inequalities, adding slack variables or subtracting surplus variables as needed.
- $\mathrm{x}_{1}+\mathrm{x}_{2}+\mathrm{x}_{3}+\mathrm{s}_{2}=23$
$\mathrm{x}_{1}+\mathrm{x}_{2}+\mathrm{x}_{3}-\mathrm{s}_{2}=23$
$\mathrm{x}_{1}+\mathrm{x}_{2}+\mathrm{s}_{3}=14$
$\mathrm{x}_{1}+\mathrm{x}_{2}-\mathrm{s}_{3}=14$

A) $2 x_{1}+x_{3}+s_{1}=52$
$2 \mathrm{x}_{1}+\mathrm{x}_{2}-\mathrm{s}_{2}=22$
$\mathrm{x}_{1}+\mathrm{x}_{3}-\mathrm{s}_{3}=20$
B) $2 x_{1}+x_{3}-s_{1}=52$
$2 \mathrm{x}_{1}+\mathrm{x}_{2}+\mathrm{s}_{2}=22$
$\mathrm{x}_{1}+\mathrm{x}_{3}+\mathrm{s}_{3}=20$
C) $2 x_{1}+x_{3}+s_{1}=52$
$2 \mathrm{x}_{1}+\mathrm{x}_{2}+\mathrm{s}_{2}=22$
$\mathrm{x}_{1}+\mathrm{x} 3+\mathrm{s}_{3}=20$
D) $2 x_{1}+x_{3}-s_{1}=52$
$2 \mathrm{x}_{1}+\mathrm{x}_{2}-\mathrm{s}_{2}=22$
$\mathrm{x}_{1}+\mathrm{x}_{3}-\mathrm{s}_{3}=20$
