Accepted Answer

\[\sqrt{x} + 60 = 2000 : 8\]
1. \(\sqrt{x} + 60 = 250\)
2. \(\sqrt{x} = 250 - 60\)
3. \(\sqrt{x} = 190\)
4. \[(\sqrt{x})^2 = (190)^2\]
5. \[x = 36100\]
\[350 : x = 50\]
1. \[x = 350 : 50\]
2. \[x = 7\]
\[720 : x = 20\]
1. \[x = 720 : 20\]
2. \[x = 36\]
\[\sqrt{x} \cdot 30 = 150\]
1. \[\sqrt{x} = 150 : 30\]
2. \[\sqrt{x} = 5\]
3. \[(\sqrt{x})^2 = 5^2\]
4. \[x = 25\]
