The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = \frac{511}{8}$$
Divide both parts of the equation by -2
We get the answer: x = -511/16
(1/2)^3-2*x = 64
Expand brackets in the left part
1/2^3-2*x = 64
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = \frac{511}{8}$$
Divide both parts of the equation by -2
x = 511/8 / (-2)
We get the answer: x = -511/16
