The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = 4$$
Divide both parts of the equation by -4
We get the answer: x = -1
-4*x+3 = 7
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = 4$$
Divide both parts of the equation by -4
x = 4 / (-4)
We get the answer: x = -1
