(50-3x)-(-20+4x) = 0
50-3x+20-4x = 0
70-7x = 0
-7x = -70
7x = 70
x = 10
Answer: I’m pretty sure the common factor is 15x3y
It’s c just try think of it logically
So Maurice would have 2N nickels
Total number of coins is N + 2N + 9 = 3N + 9
Each nickel is 5 pennies
3N of nickels = 15N pennies
-----------
Their worth is 84 cents
15N + 9 = 84
15N = 75
N = 75/15 = 5
N = 5
This means Nina has 5 nickels.

3
Step-by-step explanation:
I think you set them equal to each other.so you would do 16x+2=15x+5 and you would get x=3. I hope this helps out! ☺️
