The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$17 x = 20 x + 17$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = 17$$
Divide both parts of the equation by -3
We get the answer: x = -17/3
17*x-8 = 20*x+9
Move free summands (without x)
from left part to right part, we given:
$$17 x = 20 x + 17$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = 17$$
Divide both parts of the equation by -3
x = 17 / (-3)
We get the answer: x = -17/3
