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:
$$6 x = 30$$
Divide both parts of the equation by 6
We get the answer: x = 5
13-6*(3-x) = 25
Expand brackets in the left part
13-6*3+6*x = 25
Looking for similar summands in the left part:
-5 + 6*x = 25
Move free summands (without x)
from left part to right part, we given:
$$6 x = 30$$
Divide both parts of the equation by 6
x = 30 / (6)
We get the answer: x = 5
