The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = -4$$
Divide both parts of the equation by -6
We get the answer: x = 2/3
9-6*x = 5
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = -4$$
Divide both parts of the equation by -6
x = -4 / (-6)
We get the answer: x = 2/3
