$$x + \left(- \frac{x}{4} + 4\right) = - \frac{5^{2}}{15} + 1$$
Detail solution
Given the linear equation:
4-x/4+x = 1-5^2/15

Looking for similar summands in the left part:
4 + 3*x/4 = 1-5^2/15

Move free summands (without x)
from left part to right part, we given:
$$\frac{3 x}{4} = - \frac{14}{3}$$
Divide both parts of the equation by 3/4
x = -14/3 / (3/4)

We get the answer: x = -56/9
