The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$13 x = 27 x + 10$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-14\right) x = 10$$
Divide both parts of the equation by -14
We get the answer: x = -5/7
13*x+8 = 27*x+18
Move free summands (without x)
from left part to right part, we given:
$$13 x = 27 x + 10$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-14\right) x = 10$$
Divide both parts of the equation by -14
x = 10 / (-14)
We get the answer: x = -5/7
