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 28
We get the answer: y = 17/500
y+27*y = (119/125)
Expand brackets in the right part
y+27*y = 119/125
Looking for similar summands in the left part:
28*y = 119/125
Divide both parts of the equation by 28
y = 119/125 / (28)
We get the answer: y = 17/500
