The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$2 x = 10 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-8\right) x = 4$$
Divide both parts of the equation by -8
We get the answer: x = -1/2
-1+2*x = 10*x+3
Move free summands (without x)
from left part to right part, we given:
$$2 x = 10 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-8\right) x = 4$$
Divide both parts of the equation by -8
x = 4 / (-8)
We get the answer: x = -1/2
