The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$6 x = \frac{5 x}{3} - 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{13 x}{3} = -9$$
Divide both parts of the equation by 13/3
We get the answer: x = -27/13
6*x+8/2+5 = 5*x/3
Looking for similar summands in the left part:
9 + 6*x = 5*x/3
Move free summands (without x)
from left part to right part, we given:
$$6 x = \frac{5 x}{3} - 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{13 x}{3} = -9$$
Divide both parts of the equation by 13/3
x = -9 / (13/3)
We get the answer: x = -27/13
