#w<=4#

Explanation:

#8(w-2)-7<=9#

add 7 to both sides:

#8(w-2)<=16#

divide both sides by 8:

#w-2<=2#

add 2 to both sides:

#w<=4#

#w<=4#

Explanation:

#"distribute the bracket"#

#8w-16-7<=9#

#rArr8w-23<=9#

#"add 23 to both sides"#

#8wcancel(-23)cancel(+23)<=9+23#

#rArr8w<=32#

#"divide both sides by 8"#

#(cancel(8) w)/cancel(8)<=32/8#

#rArrw<=4" is the solution"#
