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:
$$3 x = - x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = -2$$
Divide both parts of the equation by 4
We get the answer: x = -1/2
-3+3*x+5 = -x
Looking for similar summands in the left part:
2 + 3*x = -x
Move free summands (without x)
from left part to right part, we given:
$$3 x = - x - 2$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = -2$$
Divide both parts of the equation by 4
x = -2 / (4)
We get the answer: x = -1/2
