The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$x = \frac{x}{5} + 220$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{4 x}{5} = 220$$
Divide both parts of the equation by 4/5
We get the answer: x = 275
x-220 = x/5
Move free summands (without x)
from left part to right part, we given:
$$x = \frac{x}{5} + 220$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{4 x}{5} = 220$$
Divide both parts of the equation by 4/5
x = 220 / (4/5)
We get the answer: x = 275
