The solution
Detail solution
Given the linear equation:
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$- x = -453$$
Divide both parts of the equation by -1
We get the answer: x = 453
1000-x = 600-53
Looking for similar summands in the right part:
1000 - x = 547
Move free summands (without x)
from left part to right part, we given:
$$- x = -453$$
Divide both parts of the equation by -1
x = -453 / (-1)
We get the answer: x = 453
