The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$9 x = 16 - 17 x$$
Move the summands with the unknown x
from the right part to the left part:
$$26 x = 16$$
Divide both parts of the equation by 26
We get the answer: x = 8/13
-7+9*x = -17*x+9
Move free summands (without x)
from left part to right part, we given:
$$9 x = 16 - 17 x$$
Move the summands with the unknown x
from the right part to the left part:
$$26 x = 16$$
Divide both parts of the equation by 26
x = 16 / (26)
We get the answer: x = 8/13
