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:
$$- 6 x = 4 x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = -5$$
Divide both parts of the equation by -10
We get the answer: x = 1/2
17-6*(x+2) = 4*x
Expand brackets in the left part
17-6*x-6*2 = 4*x
Looking for similar summands in the left part:
5 - 6*x = 4*x
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 4 x - 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-10\right) x = -5$$
Divide both parts of the equation by -10
x = -5 / (-10)
We get the answer: x = 1/2
