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:
$$- 2 x = 11$$
Divide both parts of the equation by -2
We get the answer: x = -11/2
4*x+2*(1-3*x) = 13
Expand brackets in the left part
4*x+2*1-2*3*x = 13
Looking for similar summands in the left part:
2 - 2*x = 13
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 11$$
Divide both parts of the equation by -2
x = 11 / (-2)
We get the answer: x = -11/2
