$$- \frac{x}{7} + 3 = \frac{x}{3}$$
Detail solution
Given the linear equation:
3-x/7 = x/3

Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{7} = \frac{x}{3} - 3$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-10\right) x}{21} = -3$$
Divide both parts of the equation by -10/21
x = -3 / (-10/21)

We get the answer: x = 63/10
