How do you solve the inequality #5(4y-5) >75#?
1 Answer
Explanation:
#5(4y-5) > 75#
#4y-5> 15#
#4y> 20 implies y>5#
Alternatively, you can
- Expand the bracket
#20y -25 > 75#
- Add
#25# to both sides of the inequality
#20y > 100#
- Divide both sides by
#20#
#(cancel(20)y)/cancel(20) > 100/20#
#y > 5#
