The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{x}{3} + 2$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-1\right) x}{3} = 2$$
Divide both parts of the equation by -1/3
We get the answer: x = -6
2 = 1/3*x+4
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{x}{3} + 2$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-1\right) x}{3} = 2$$
Divide both parts of the equation by -1/3
x = 2 / (-1/3)
We get the answer: x = -6
