The solution
Detail solution
Given the linear equation:
Expand brackets 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
2*(x+3) = 12
Expand brackets in the left part
2*x+2*3 = 12
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
