The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$50 x = 270$$
Divide both parts of the equation by 50
We get the answer: x = 27/5
50*x-60 = 210
Move free summands (without x)
from left part to right part, we given:
$$50 x = 270$$
Divide both parts of the equation by 50
x = 270 / (50)
We get the answer: x = 27/5
