The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- x = -4200$$
Divide both parts of the equation by -1
We get the answer: x = 4200
4900-x = 5600/8
Move free summands (without x)
from left part to right part, we given:
$$- x = -4200$$
Divide both parts of the equation by -1
x = -4200 / (-1)
We get the answer: x = 4200
