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:
$$2 x = 6$$
Divide both parts of the equation by 2
We get the answer: x = 3
5*x-(3*x-18) = 24
Expand brackets in the left part
5*x-3*x+18 = 24
Looking for similar summands in the left part:
18 + 2*x = 24
Move free summands (without x)
from left part to right part, we given:
$$2 x = 6$$
Divide both parts of the equation by 2
x = 6 / (2)
We get the answer: x = 3
