Answer:
74 Labtops
Explanation:
you first have to subtract 6 from 142
142-6= 136
divide 136 by two.... for the labtops and the computers.
136 รท 2 = 68
68 is the number of desktops...to find the number of labtops you just need to add 6 again.
68 + 6 = 74 Labtops
To check your answer you can just add
74+68 and if it equals to what you started with then that's your answer
74 + 68 = 142
