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:
$$\frac{2 x}{3} = -4$$
Divide both parts of the equation by 2/3
We get the answer: x = -6
x+7-x/3 = 3
Looking for similar summands in the left part:
7 + 2*x/3 = 3
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{3} = -4$$
Divide both parts of the equation by 2/3
x = -4 / (2/3)
We get the answer: x = -6
