Answer:
$261
Step-by-step explanation:
We are given that Mary Moneypenny went to her bank each week and opened a club account.
She deposited money per time period=$21.75
She made total deposits before interest was credit=12
We have to find out total deposits money in her account before interest was credited.
We are multiplying number of deposits with deposit per time period to obtain the value of total deposits
She would have total deposit money before interest was credit==$261
Hence, the balance would be $ 261 before interest was credited.

Answer:
(2, -7)
x = 2
y = -7
Step-by-step explanation:
Let's solve this system of equations by elimination.
Start by multiplying the first equation by 2:
Next, multiply the second equation by 3:
Notice that both equations now have a "6y", meaning we can subtract both equations and thereby eliminating the variable "y" from the equation:
Divide both sides by 23
Substitute 2 for "x" to solve for "y".
Subtract 8 from both sides:
Divide both sides by 3:
Therefore the answer is:
Additional Comments:
Note that we can only divide, subtract, multiply, or add both sides of the equation by the same quantity due to the Division, Subtraction, Multiplication, or Addition Property of Equality. These properties state that if you divide/subtract/multiply/add one side of the equation by one quantity, you must do the same to the other side of the equation so that it remains an equation.
