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:
$$\frac{2 x}{3} = 0$$
Divide both parts of the equation by 2/3
We get the answer: x = 0
x+7-x/3 = 7
Looking for similar summands in the left part:
7 + 2*x/3 = 7
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{3} = 0$$
Divide both parts of the equation by 2/3
x = 0 / (2/3)
We get the answer: x = 0
