The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = - 4 x - 13$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -13$$
Divide both parts of the equation by -2
We get the answer: x = 13/2
7-6*x = -4*x-6
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = - 4 x - 13$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-2\right) x = -13$$
Divide both parts of the equation by -2
x = -13 / (-2)
We get the answer: x = 13/2
