The solution
You have entered
[src]
x + -2*x + 3*x + 4*x + 5 = 1
$$x + \left(\left(4 x + \left(- 2 x + 3 x\right)\right) + 5\right) = 1$$
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:
$$6 x = -4$$
Divide both parts of the equation by 6
We get the answer: x = -2/3
x-(2*x-3*x-4*x-5) = 1
Expand brackets in the left part
x-2*x+3*x+4*x+5 = 1
Looking for similar summands in the left part:
5 + 6*x = 1
Move free summands (without x)
from left part to right part, we given:
$$6 x = -4$$
Divide both parts of the equation by 6
x = -4 / (6)
We get the answer: x = -2/3
