The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$13 x = 26 x + 26$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-13\right) x = 26$$
Divide both parts of the equation by -13
We get the answer: x = -2
9+13*x = 35+26*x
Move free summands (without x)
from left part to right part, we given:
$$13 x = 26 x + 26$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-13\right) x = 26$$
Divide both parts of the equation by -13
x = 26 / (-13)
We get the answer: x = -2
