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:
$$- x = -14$$
Divide both parts of the equation by -1
We get the answer: x = 14
15-(x-4) = 5
Expand brackets in the left part
15-x+4 = 5
Looking for similar summands in the left part:
19 - x = 5
Move free summands (without x)
from left part to right part, we given:
$$- x = -14$$
Divide both parts of the equation by -1
x = -14 / (-1)
We get the answer: x = 14
