39*x 23*x 4 ---- - ---- + - = 12 5 5 5
$$\left(- \frac{23 x}{5} + \frac{39 x}{5}\right) + \frac{4}{5} = 12$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$\frac{16 x}{5} = \frac{56}{5}$$
Divide both parts of the equation by 16/5
We get the answer: x = 7/2
(39/5)*x-(23/5)*x+(4/5) = 12
Expand brackets in the left part
39/5x-23/5x+4/5 = 12
Looking for similar summands in the left part:
4/5 + 16*x/5 = 12
Move free summands (without x)
from left part to right part, we given:
$$\frac{16 x}{5} = \frac{56}{5}$$
Divide both parts of the equation by 16/5
x = 56/5 / (16/5)
We get the answer: x = 7/2
