The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$19 x = 38$$
Divide both parts of the equation by 19
We get the answer: x = 2
23*x-20-4*x = 18
Looking for similar summands in the left part:
-20 + 19*x = 18
Move free summands (without x)
from left part to right part, we given:
$$19 x = 38$$
Divide both parts of the equation by 19
x = 38 / (19)
We get the answer: x = 2
