The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$\frac{11 x}{2} = -2$$
Divide both parts of the equation by 11/2
We get the answer: x = -4/11
11/2*x+7 = 5
Move free summands (without x)
from left part to right part, we given:
$$\frac{11 x}{2} = -2$$
Divide both parts of the equation by 11/2
x = -2 / (11/2)
We get the answer: x = -4/11
