The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = -1$$
Divide both parts of the equation by -3
We get the answer: x = 1/3
4-3*x = 3
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = -1$$
Divide both parts of the equation by -3
x = -1 / (-3)
We get the answer: x = 1/3
