The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = -3$$
Divide both parts of the equation by -3
We get the answer: x = 1
x+3-4*x = 0
Looking for similar summands in the left part:
3 - 3*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = -3$$
Divide both parts of the equation by -3
x = -3 / (-3)
We get the answer: x = 1
