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:
$$x = -6$$
We get the answer: x = -6
(x+3)-17 = -20
Expand brackets in the left part
x+3-17 = -20
Looking for similar summands in the left part:
-14 + x = -20
Move free summands (without x)
from left part to right part, we given:
$$x = -6$$
We get the answer: x = -6
