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:
$$- 3 x = 1$$
Divide both parts of the equation by -3
We get the answer: x = -1/3
x-2*(2*x-5) = 11
Expand brackets in the left part
x-2*2*x+2*5 = 11
Looking for similar summands in the left part:
10 - 3*x = 11
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 1$$
Divide both parts of the equation by -3
x = 1 / (-3)
We get the answer: x = -1/3
