Fill the following blanks with correct numbers :
`7xx…=-84`

Answer

To solve the equation \( 7xx = -84 \), we need to find the value of \( x \) such that when we multiply 7 by \( x \), we get -84.

### Step 1: Set up the equation
We can rewrite the equation as:
\[ 7 \times x = -84 \]

### Step 2: Isolate \( x \)
To find \( x \), we need to divide both sides of the equation by 7:
\[ x = \frac{-84}{7} \]

### Step 3: Perform the division
Now, we will divide -84 by 7:
- First, we divide the absolute values: \( 84 \div 7 = 12 \).
- Since we are dividing a negative number by a positive number, the result will be negative:
\[ x = -12 \]

### Conclusion
Thus, the value of \( x \) that fills the blank is:
\[ x = -12 \]

So, the complete equation is:
\[ 7 \times (-12) = -84 \]
