Answer:
y=45-3x
Step-by-step explanation:
we want y, which is the number of hours left. to find this, we take:
hours left=total # of hours required - hours worked/day
so:
y=45-3x
(because x could be any number: 2 days, 3 days, etc.)
(-3)(-8)(-1)= -24
(-3)+(-8)+(-1)= -12
-1/5n+7=2
-7 -7
-1/5n= -5
Multiplied by 5/-1
Answer is 25
n=25
