Rewrite the System of Inequalities, Adding Slack Variables or Subtracting $15 x_{1}+3 x_{2} \leq 47$

Multiple Choice

Rewrite the system of inequalities, adding slack variables or subtracting surplus variables as needed.
- $15 x_{1}+3 x_{2} \leq 47$
$12 \mathrm{x}_{1}+6 \mathrm{x}_{2} \geq 63$

A) $15 x_{1}+3 x_{2}+s_{1}=47$
$12 x_{1}+6 x_{2}-s_{2}=63$
B) $15 x_{1}+3 x_{2}+s_{1}=47$
$12 \mathrm{x}_{1}+6 \mathrm{x}_{2}+\mathrm{s}_{2}=63$
C) $15 x_{1}+3 x_{2}-s 1=47$
$12 \mathrm{x}_{1}+6 \mathrm{x}_{2}-\mathrm{s}_{2}=63$
D) $15 x_{1}+3 x_{2}-s 1=47$
$12 \mathrm{x}_{1}+6 \mathrm{x}_{2}+\mathrm{s}_{2}=63$
