The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$2 x = \frac{32}{3}$$
Divide both parts of the equation by 2
We get the answer: x = 16/3
2*x+1/3-2 = 9
Looking for similar summands in the left part:
-5/3 + 2*x = 9
Move free summands (without x)
from left part to right part, we given:
$$2 x = \frac{32}{3}$$
Divide both parts of the equation by 2
x = 32/3 / (2)
We get the answer: x = 16/3
