A)
Given that Hugo works 'x' hours each week,
[tex]T_{H_{}}=x[/tex]Patricia works 3 more than twice the working time of Hugo,
[tex]\begin{gathered} T_P=3+2(T_H) \\ T_P=3+2(x) \\ T_P=2x+3 \end{gathered}[/tex]Sun works 2 hours less than Hugo,
[tex]\begin{gathered} T_S=T_H-2 \\ T_S=x-2 \end{gathered}[/tex]
