Rewrite the System of Inequalities, Adding Slack Variables or Subtracting $2 x_{1}+5 x_{2} \leq 7$

Rewrite the system of inequalities, adding slack variables or subtracting surplus variables as needed.
- $2 x_{1}+5 x_{2} \leq 7$
$x_{1}+3 x_{2} \geq 5$

A) $2 x_{1}+5 x_{2}-s_{1}=7$
$\mathrm{x}_{1}+3 \mathrm{x}_{2}+\mathrm{s}_{2}=5$
B) $2 x_{1}+5 x_{2}+s_{1}=7$
$\mathrm{x}_{1}+3 \mathrm{x}_{2}+\mathrm{s}_{2}=5$
C) $2 x_{1}+5 x_{2}-s_{1}=7$
$\mathrm{x}_{1}+3 \mathrm{x}_{2}-\mathrm{s}_{2}=5$
D) $2 x_{1}+5 x_{2}+s_{1}=7$
$\mathrm{x}_{1}+3 \mathrm{x}_{2}-\mathrm{s}_{2}=5$
