The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 48$$
Divide both parts of the equation by -2
We get the answer: x = -24
2^4-2*x = 64
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = 48$$
Divide both parts of the equation by -2
x = 48 / (-2)
We get the answer: x = -24
