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 73/50
We get the answer: x = 4500/73
x+(23/10)/5*x = 90
Expand brackets in the left part
x+23/10/5*x = 90
Looking for similar summands in the left part:
73*x/50 = 90
Divide both parts of the equation by 73/50
x = 90 / (73/50)
We get the answer: x = 4500/73
