The solution
Detail solution
Given the linear equation:
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 2 n + 16$$
Divide both parts of the equation by 4
We get the answer: x = 4 + n/2
2^2*x-2*n = 16
Move the summands with the other variables
from left part to right part, we given:
$$4 x = 2 n + 16$$
Divide both parts of the equation by 4
x = 16 + 2*n / (4)
We get the answer: x = 4 + n/2
