Answer:

  1. ) x = 5
  2. ) x = 13
  3. ) x = 4
  4. ) x = 0
  5. ) x = 5

Step-by-step Solution:

[tex] \bold{1) \: } \boxed{ \begin{array}{}\tt x + 4 = 9 \\\tt x + 4 −4 = 9 −4 \\ \tt x = 5\end{array}{}}[/tex]

[tex] \bold{2) \: } \boxed{ \begin{array}{}\tt x + 7 = 20 \\ \tt x + 7−7 = 20−7 \\ \tt x = 13\end{array}{}}[/tex]

[tex] \bold{ 3)\: }\boxed{ \begin{array}{}\tt x + 8 = 12 \\\tt x + 8 - 8 = 12 - 8 \\\tt x = 8 \end{array}{}}[/tex]

[tex] \bold{4) \: } \tt \boxed{ \begin{array}{}\tt x + 9 = 9 \\\tt x + 9 - 9 = 9 - 9 \\ \tt x = 0 \end{array}{}}[/tex]

[tex] \bold{5) \: } \tt \boxed{ \begin{array}{}\tt x + 2 = 7 \\\tt x + 2 - 2 = 7 - 2 \\\tt x = 5 \end{array}{}}[/tex]
