Solution:
The equation provided in the image is $$ \sqrt{x} - 2 - 1 = 0 $$To solve for x, follow these steps:1. Combine the constants on the left side:$$ \sqrt{x} - 3 = 0 $$2. Isolate the square root:$$ \sqrt{x} = 3 $$3. Square both sides to eliminate the square root:$$ (\sqrt{x})^2 = 3^2 $$$$ x = 9 $$The solution to the equation is $$ x = 9 $$.
