The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$3 x = 6 x - 8$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = -8$$
Divide both parts of the equation by -3
We get the answer: x = 8/3
5*x-2*(x-4) = 6*x
Expand brackets in the left part
5*x-2*x+2*4 = 6*x
Looking for similar summands in the left part:
8 + 3*x = 6*x
Move free summands (without x)
from left part to right part, we given:
$$3 x = 6 x - 8$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = -8$$
Divide both parts of the equation by -3
x = -8 / (-3)
We get the answer: x = 8/3
