The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the left part:
Divide both parts of the equation by 3/10
We get the answer: x = 1/3
1/2*x-1/5*x = (1/10)
Expand brackets in the right part
1/2*x-1/5*x = 1/10
Looking for similar summands in the left part:
3*x/10 = 1/10
Divide both parts of the equation by 3/10
x = 1/10 / (3/10)
We get the answer: x = 1/3
