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:
$$- 5 x = -39$$
Divide both parts of the equation by -5
We get the answer: x = 39/5
-5*x+12+27 = 0
Looking for similar summands in the left part:
39 - 5*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = -39$$
Divide both parts of the equation by -5
x = -39 / (-5)
We get the answer: x = 39/5
