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:
$$\frac{3 x}{2} = \frac{19}{3}$$
Divide both parts of the equation by 3/2
We get the answer: x = 38/9
x-4/3+x/2 = 5
Looking for similar summands in the left part:
-4/3 + 3*x/2 = 5
Move free summands (without x)
from left part to right part, we given:
$$\frac{3 x}{2} = \frac{19}{3}$$
Divide both parts of the equation by 3/2
x = 19/3 / (3/2)
We get the answer: x = 38/9
