Sum of two integers is -35. If one of them is 15, then other one is

Options

A. 20
B. `-20`
C. `-50`
D. 50

Answer

To find the other integer when the sum of two integers is -35 and one of them is 15, we can follow these steps:

### Step 1: Write the equation based on the information given.
We know that the sum of two integers is -35. If we let the other integer be represented as \( x \), we can write the equation as:
\[ 15 + x = -35 \]

### Step 2: Isolate the variable \( x \).
To find \( x \), we need to isolate it on one side of the equation. We can do this by subtracting 15 from both sides:
\[ x = -35 - 15 \]

### Step 3: Perform the subtraction.
Now, we will calculate the right side:
\[ x = -35 - 15 = -50 \]

### Step 4: State the final answer.
Thus, the other integer is:
\[ x = -50 \]

### Summary of the Solution:
The other integer is -50.
