The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- x = -3$$
Divide both parts of the equation by -1
We get the answer: x = 3
7-x = 4
Move free summands (without x)
from left part to right part, we given:
$$- x = -3$$
Divide both parts of the equation by -1
x = -3 / (-1)
We get the answer: x = 3
