The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$10 x = 8$$
Divide both parts of the equation by 10
We get the answer: x = 4/5
10*x-8 = 0
Move free summands (without x)
from left part to right part, we given:
$$10 x = 8$$
Divide both parts of the equation by 10
x = 8 / (10)
We get the answer: x = 4/5
