The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$x = -14$$
We get the answer: x = -14
x+(31/5) = -(39/5)
Expand brackets in the left part
x+31/5 = -(39/5)
Expand brackets in the right part
x+31/5 = -39/5
Move free summands (without x)
from left part to right part, we given:
$$x = -14$$
We get the answer: x = -14
