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:
$$- 4 x = 4 x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-8\right) x = -5$$
Divide both parts of the equation by -8
We get the answer: x = 5/8
x-5*x+3 = 4*x-2
Looking for similar summands in the left part:
3 - 4*x = 4*x-2
Move free summands (without x)
from left part to right part, we given:
$$- 4 x = 4 x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-8\right) x = -5$$
Divide both parts of the equation by -8
x = -5 / (-8)
We get the answer: x = 5/8
