The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Divide both parts of the equation by 13/10
We get the answer: x = 30000/13
x+(x*30*(1/100)) = 3000
Expand brackets in the left part
x+x*30*+1/100) = 3000
Looking for similar summands in the left part:
13*x/10 = 3000
Divide both parts of the equation by 13/10
x = 3000 / (13/10)
We get the answer: x = 30000/13
