Step-by-step explanation:
Answer:
8-x0-36
Step-by-step explanation:
subtract 4x from both sides
-2y=14-4x
divide each side by -2
y=2x+7
y = number of days
35.50 + 18.25 y = 163.25
18.25 y = 163.25 - 35.50
18.25y = 127.75
y = 127.75 / 18.25
y = 7
so Martin has hired the machine for 8 days
( first day paid 35.50), then 7 days for 18.25
