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:
$$- x = -15$$
Divide both parts of the equation by -1
We get the answer: x = 15
65-(x+38) = 12
Expand brackets in the left part
65-x-38 = 12
Looking for similar summands in the left part:
27 - x = 12
Move free summands (without x)
from left part to right part, we given:
$$- x = -15$$
Divide both parts of the equation by -1
x = -15 / (-1)
We get the answer: x = 15
