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
2*(x+2)-10 = 0
Expand brackets in the left part
2*x+2*2-10 = 0
Looking for similar summands in the left part:
-6 + 2*x = 0
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
