In the following questions two equation numbered I and II are given You have to solve both equations and . . . . .
(i) `x-sqrt(121)=0`
(ii) `y^(2)-121=0`

Answer

To solve the given equations, we will follow these steps:

### Step 1: Solve the first equation
The first equation is:
\[ x - \sqrt{121} = 0 \]

To isolate \( x \), we will add \( \sqrt{121} \) to both sides:
\[ x = \sqrt{121} \]

### Step 2: Calculate \( \sqrt{121} \)
Now, we need to calculate \( \sqrt{121} \):
\[ \sqrt{121} = 11 \]

Thus, from the first equation, we have:
\[ x = 11 \]

### Step 3: Solve the second equation
The second equation is:
\[ y^2 - 121 = 0 \]

To isolate \( y^2 \), we will add \( 121 \) to both sides:
\[ y^2 = 121 \]

### Step 4: Take the square root of both sides
Now, we take the square root of both sides:
\[ y = \sqrt{121} \]
or
\[ y = -\sqrt{121} \]

### Step 5: Calculate \( \sqrt{121} \)
As calculated earlier, \( \sqrt{121} = 11 \). Therefore, we have two possible values for \( y \):
\[ y = 11 \]
or
\[ y = -11 \]

### Final Answers
From the above steps, we conclude:
- For the first equation: \( x = 11 \)
- For the second equation: \( y = 11 \) or \( y = -11 \)

### Summary of Solutions
- \( x = 11 \)
- \( y = 11 \) or \( y = -11 \)
