The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by -1
We get the answer: x = -2
log(1)/9 = 2+x
Expand brackets in the left part
log1/9 = 2+x
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by -1
x = 2 / (-1)
We get the answer: x = -2
