The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$\frac{4 x}{9} = \frac{x}{6} - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{5 x}{18} = -5$$
Divide both parts of the equation by 5/18
We get the answer: x = -18
4/9*x+14 = 1/6*x+9
Move free summands (without x)
from left part to right part, we given:
$$\frac{4 x}{9} = \frac{x}{6} - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{5 x}{18} = -5$$
Divide both parts of the equation by 5/18
x = -5 / (5/18)
We get the answer: x = -18
