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:
$$3 x = 15$$
Divide both parts of the equation by 3
We get the answer: x = 5
x-2*(5-x) = 5
Expand brackets in the left part
x-2*5+2*x = 5
Looking for similar summands in the left part:
-10 + 3*x = 5
Move free summands (without x)
from left part to right part, we given:
$$3 x = 15$$
Divide both parts of the equation by 3
x = 15 / (3)
We get the answer: x = 5
