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