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:
$$5 x = 55$$
Divide both parts of the equation by 5
We get the answer: x = 11
9*x-4*x+39 = 94
Looking for similar summands in the left part:
39 + 5*x = 94
Move free summands (without x)
from left part to right part, we given:
$$5 x = 55$$
Divide both parts of the equation by 5
x = 55 / (5)
We get the answer: x = 11
