The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$4 x = -41$$
Divide both parts of the equation by 4
We get the answer: x = -41/4
4*(x+10) = -1
Expand brackets in the left part
4*x+4*10 = -1
Move free summands (without x)
from left part to right part, we given:
$$4 x = -41$$
Divide both parts of the equation by 4
x = -41 / (4)
We get the answer: x = -41/4
