3*(4*x - 8/5)
------------- = x + 8/5

$$\frac{3 \cdot \left(4 x - \frac{8}{5}\right)}{2} = x + \frac{8}{5}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$6 x = x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 4$$
Divide both parts of the equation by 5
We get the answer: x = 4/5
(3/2)*(4*x-(8/5)) = x+(8/5)
Expand brackets in the left part
3/24*x+8/5) = x+(8/5)
Expand brackets in the right part
3/24*x+8/5) = x+8/5
Move free summands (without x)
from left part to right part, we given:
$$6 x = x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 4$$
Divide both parts of the equation by 5
x = 4 / (5)
We get the answer: x = 4/5
