The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{33 x}{100} - 200$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-33\right) x}{100} = -200$$
Divide both parts of the equation by -33/100
We get the answer: x = 20000/33
200 = x*(33/100)
Expand brackets in the right part
200 = x33/100
Move free summands (without x)
from left part to right part, we given:
$$0 = \frac{33 x}{100} - 200$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-33\right) x}{100} = -200$$
Divide both parts of the equation by -33/100
x = -200 / (-33/100)
We get the answer: x = 20000/33
