Math, microeconomics or criminal justice
8/7y=1/10+2/5= 1/10+4/10= 5/10=1/2
(7/8)(8/7y)=(7/8)(1/2)
1/y = 7/16
y= 16/7 that's the correct answer to the problem as you've literally written it
but maybe you really meant (8/7)y -2/5 = 1/10 then
y = (1/2)(7/8)
y = 7/16
a lot of people seem to write (8/7)y as 8/7y leaving out a needed parentheses
