x+x•4=65

To solve the equation \( x + x \cdot 4 = 65 \), we can first simplify the left side:

1. Rewrite \( x \cdot 4 \) as \( 4x \): \[ x + 4x = 65 \]

2. Combine like terms: \[ 5x = 65 \]

3. Now, divide both sides by 5 to solve for \( x \): \[ x = \frac{65}{5} \] \[ x = 13 \]

So, the solution is \( x = 13 \).
