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:
$$\frac{6 x}{5} = 3$$
Divide both parts of the equation by 6/5
We get the answer: x = 5/2
x = 3-(x/5)
Expand brackets in the right part
x = 3-x/5
Move the summands with the unknown x
from the right part to the left part:
$$\frac{6 x}{5} = 3$$
Divide both parts of the equation by 6/5
x = 3 / (6/5)
We get the answer: x = 5/2
