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:
$$\frac{11 x}{3} = 7$$
Divide both parts of the equation by 11/3
We get the answer: x = 21/11
2*x+5/3*x-1 = 6
Looking for similar summands in the left part:
-1 + 11*x/3 = 6
Move free summands (without x)
from left part to right part, we given:
$$\frac{11 x}{3} = 7$$
Divide both parts of the equation by 11/3
x = 7 / (11/3)
We get the answer: x = 21/11
