The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$11 x = x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = 9$$
Divide both parts of the equation by 10
We get the answer: x = 9/10
11*x-9 = x
Move free summands (without x)
from left part to right part, we given:
$$11 x = x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = 9$$
Divide both parts of the equation by 10
x = 9 / (10)
We get the answer: x = 9/10
