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:
$$5 x = 22$$
Divide both parts of the equation by 5
We get the answer: x = 22/5
x+2*2*x-8-14 = 0
Looking for similar summands in the left part:
-22 + 5*x = 0
Move free summands (without x)
from left part to right part, we given:
$$5 x = 22$$
Divide both parts of the equation by 5
x = 22 / (5)
We get the answer: x = 22/5
