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