Answer:
Step-by-step explanation:
-3w + 7 = -14
subtract 7 from both sides
-3w + 7 - 7 = - 14 -7
-3w = -21
divide both sides by (-3)
-3w/-3 = -21/-3
w = 7
In short:
-3w + 7 = -14
-3w = -14 - 7
-3w = -21
w = -21/-3
w = 7

so you need <u>50</u> people!!!
You would probably find it on the altitude or height.
