The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$7 x = -8$$
Divide both parts of the equation by 7
We get the answer: x = -8/7
8+7*x = 0
Move free summands (without x)
from left part to right part, we given:
$$7 x = -8$$
Divide both parts of the equation by 7
x = -8 / (7)
We get the answer: x = -8/7
