Answer:
[tex]\large \textsf{Read below}[/tex]
Step-by-step explanation:
[tex]\large \text{$ \begin{cases}\sf 3x + 7 = 22\\\sf 2y + 1 = 15\end{cases}$}[/tex]
[tex]\large \text{$ \sf 3x = 22- 7 $}[/tex]
[tex]\large \text{$ \sf 3x = 15$}[/tex]
[tex]\large \text{$ \sf x = \dfrac{15}{3}$}[/tex]
[tex]\large \boxed{\text{$ \sf x = 5$}}[/tex]
[tex]\large \text{$ \sf 2y = 15 - 1 $}[/tex]
[tex]\large \text{$ \sf 2y = 14$}[/tex]
[tex]\large \text{$ \sf y = \dfrac{14}{2}$}[/tex]
[tex]\large \boxed{\text{$ \sf y = 7$}}[/tex]
