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:
$$- 7 x = -1$$
Divide both parts of the equation by -7
We get the answer: x = 1/7
-2*x-5*x+1 = 0
Looking for similar summands in the left part:
1 - 7*x = 0
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = -1$$
Divide both parts of the equation by -7
x = -1 / (-7)
We get the answer: x = 1/7
