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:
$$- 10 x = -90$$
Divide both parts of the equation by -10
We get the answer: x = 9
-10*(x-9) = 0
Expand brackets in the left part
-10*x+10*9 = 0
Move free summands (without x)
from left part to right part, we given:
$$- 10 x = -90$$
Divide both parts of the equation by -10
x = -90 / (-10)
We get the answer: x = 9
