The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move the summands with the unknown x
from the right part to the left part:
$$\frac{3 x}{2} = \frac{1}{2}$$
Divide both parts of the equation by 3/2
We get the answer: x = 1/3
x = (1-x)/2
Expand brackets in the right part
x = 1/2-x/2
Move the summands with the unknown x
from the right part to the left part:
$$\frac{3 x}{2} = \frac{1}{2}$$
Divide both parts of the equation by 3/2
x = 1/2 / (3/2)
We get the answer: x = 1/3
