( x + 7 ) - 11 = 20 - 18

( x + 7 ) - 11= 2

x + 7           = 2 + 11

x + 7           = 13

x                 = 13 - 7

x                 = 6

$$\begin{gathered} 11 - \left|x - 6\right| = 3^2 \\ 11 - \left|x - 6\right| = 9 \\ \left|x - 6\right| = 11-9 \\ \left|x - 6\right| = 2 \\ \Rightarrow x - 6 = 2 hoặc x - 6 = -2 \\ \Rightarrow x = 8 hoặc x = 4 \end{gathered}$$

$$\begin{gathered} 1800 : \left[\left(3^x-14\right) + 30\right] = 72 \\ \left(3^x-14\right) + 30 = 1800 : 72 \\ \left(3^x-14\right) + 30 = 25 \\ 3^x-14 = 25 - 30 \\ 3^x-14 = -5 \\ 3^x = -5 + 14 \\ 3^x = 9 \\ 3^x = 3^2 \\ \Rightarrow x = 2 \end{gathered}$$
