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:
$$- 100 x = 88$$
Divide both parts of the equation by -100
We get the answer: x = -22/25
5+10*(-10*x-9) = 3
Expand brackets in the left part
5+-10*10*x-10*9 = 3
Move free summands (without x)
from left part to right part, we given:
$$- 100 x = 88$$
Divide both parts of the equation by -100
x = 88 / (-100)
We get the answer: x = -22/25
