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