The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 5
We get the answer: x = 4
5*x-7 = 13
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 5
x = 20 / (5)
We get the answer: x = 4
