The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 10 x = 5 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-15\right) x = 9$$
Divide both parts of the equation by -15
We get the answer: x = -3/5
1-10*x = 5*x+10
Move free summands (without x)
from left part to right part, we given:
$$- 10 x = 5 x + 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-15\right) x = 9$$
Divide both parts of the equation by -15
x = 9 / (-15)
We get the answer: x = -3/5
