2 answers:
1.
x/9 -1 = 5
add 1 to both side of the equation
x/9 = 6
multiply both side of the equation by 9
x = 54
2.
9y + 1 = 7
subtract 1 from each side of the equation
9y = 6
divide both side of the equation by 9
y =
divide the numerator and the denominator by 3 in order to simplify your fraction
y =
3.
3z/7 + 3 = -7
subtract 3 from each side of the equation
3z/7 = -10
multiply both side of the equation by 7
3z = -70
divide both side of the equation by 3
z =
There you go! I really hope this helped, if there's anything just let me know! :)

Step-by-step explanation:
The compound interest formula is given by:
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
Suppose that $3000 is placed in an account that pays 16% interest compounded each year.
This means, respectively, that
So
(a) Find the amount in the account at the end of 1 year.
This is A(1).
(b) Find the amount in the account at the end of 2 years.
This is A(2).
