The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 8 x - 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-14\right) x = -9$$
Divide both parts of the equation by -14
We get the answer: x = 9/14
9-6*x = 8*x
Move free summands (without x)
from left part to right part, we given:
$$- 6 x = 8 x - 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-14\right) x = -9$$
Divide both parts of the equation by -14
x = -9 / (-14)
We get the answer: x = 9/14
