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:
$$- 6 x = 11 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 11$$
Divide both parts of the equation by -1
We get the answer: x = -11
4-6*(x+2) = 3-5*x
Expand brackets in the left part
4-6*x-6*2 = 3-5*x
Looking for similar summands in the left part:
-8 - 6*x = 3-5*x
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 11 - 5 x$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = 11$$
Divide both parts of the equation by -1
x = 11 / (-1)
We get the answer: x = -11
