The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$x = 2 x - \frac{11}{8}$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = - \frac{11}{8}$$
Divide both parts of the equation by -1
We get the answer: x = 11/8
x+3/8 = 2*x-1
Move free summands (without x)
from left part to right part, we given:
$$x = 2 x - \frac{11}{8}$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = - \frac{11}{8}$$
Divide both parts of the equation by -1
x = -11/8 / (-1)
We get the answer: x = 11/8
