The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
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
5-(7*x+6) = 0
Expand brackets in the left part
5-7*x-6 = 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
