The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 8 x - 33$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-11\right) x = -33$$
Divide both parts of the equation by -11
We get the answer: x = 3
-3*x-17 = 8*x-50
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 8 x - 33$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-11\right) x = -33$$
Divide both parts of the equation by -11
x = -33 / (-11)
We get the answer: x = 3
