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:
$$x = 463$$
We get the answer: x = 463
(x-230)+257 = 490
Expand brackets in the left part
x-230+257 = 490
Looking for similar summands in the left part:
27 + x = 490
Move free summands (without x)
from left part to right part, we given:
$$x = 463$$
We get the answer: x = 463
