-x ---*(-4) = -2/25 5
$$\left(-4\right) \left(- \frac{x}{5}\right) = - \frac{2}{25}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Divide both parts of the equation by 4/5
We get the answer: x = -1/10
-(1/5)*x*(-4) = -(2/25)
Expand brackets in the left part
-1/5x-4 = -(2/25)
Expand brackets in the right part
-1/5x-4 = -2/25
Divide both parts of the equation by 4/5
x = -2/25 / (4/5)
We get the answer: x = -1/10
