Given that:
1/2x-19.7=-4.1
Adding 19.7 on both sides:
1/2x-19.7 + 19.7=-4.1 + 19.7
1/2x = 15.6
Multiplying both sides by 2:
x = 15.6 * 2
x = 31.2
So the number is 31.2

Answer:
20 newspapers
Step-by-step explanation:
First create an equation.
y = 0.75x + 45
Now substitute 60 y and solve for x.
60 = 0.75x + 45
60 - 45 = 0.75x + 45 - 45
15/0.75 = 0.75x/0.75
x = 20 newspapers
