The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$5 x = 11$$
Divide both parts of the equation by 5
We get the answer: x = 11/5
5*x-4 = 7
Move free summands (without x)
from left part to right part, we given:
$$5 x = 11$$
Divide both parts of the equation by 5
x = 11 / (5)
We get the answer: x = 11/5
