The coefficient of x in the linear equation 2(x+y)-x=7 is _________

Answer

To find the coefficient of \( x \) in the linear equation \( 2(x+y) - x = 7 \), we will follow these steps:

### Step 1: Expand the equation
Start with the original equation:
\[ 2(x+y) - x = 7 \]
Distribute the \( 2 \) across \( (x+y) \):
\[ 2x + 2y - x = 7 \]

### Step 2: Combine like terms
Now, combine the \( x \) terms:
\[ (2x - x) + 2y = 7 \]
This simplifies to:
\[ x + 2y = 7 \]

### Step 3: Identify the coefficient of \( x \)
In the simplified equation \( x + 2y = 7 \), the coefficient of \( x \) is the number that is multiplied by \( x \). Here, it is \( 1 \) (since \( x \) can be written as \( 1x \)).

### Final Answer
Thus, the coefficient of \( x \) in the linear equation is:
\[ \text{The coefficient of } x \text{ is } 1. \]
