The solution
You have entered
[src]
2*(x + 2) - 4*(6 - x) = 0
$$- 4 \left(6 - x\right) + 2 \left(x + 2\right) = 0$$
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:
$$6 x = 20$$
Divide both parts of the equation by 6
We get the answer: x = 10/3
2*(x+2)-4*(6-x) = 0
Expand brackets in the left part
2*x+2*2-4*6+4*x = 0
Looking for similar summands in the left part:
-20 + 6*x = 0
Move free summands (without x)
from left part to right part, we given:
$$6 x = 20$$
Divide both parts of the equation by 6
x = 20 / (6)
We get the answer: x = 10/3
