From my research, the original equation Fiona wrote was "y = (2/5)x - 5". It also had choices as written below:
x – 5/4y = 25/4
<span>x –5/2 y = 25/4 </span>
<span>x –5/4 y = 25/2
</span>
<span>x –5/2 y = 25/2 </span>
To obtain the possible equation Henry had written, the coefficient of x was removed, and the equation was placed in the form x + y = c. This is shown as follows:
y = (2/5) x – 5
[ <span>y = (2/5) x – 5 </span>] (5/2)
(5/2)y = x - 25/2
x - (5/2)y = 25/2
<span>Therefore, Henry's equation is x – (5/2) y = 25/2.</span>
(A) Because the employer has already deducted 20% to the value of the money, 1,600 is already the 80%. If we let x be value before the deduction, the equation would be,
1,600 = 0.80x
The value of x is $2000.
(B) We multiply 1/5 by 1,600 giving us an answer of $320.
(C) As an original payment of $2000 be deducted by 8%, the new salary would be $1840. 20% of this value is $368. Therefore, his new paycheck next month will be $1472.2.
F(6) = 3-2 = 1

Answer:
4778.69 +d-z+b
Step-by-step explanation:
Initial balance of the joint checking account = $6238.67
Deposits in a month gets added in the account = d dollars
Maintenance fee is deducted in the account = z dollars
Interest on the account is added in the account balance = b dollars
Checks written also gets deducted form the account = $1459.98
Algebraic expression so formed is
6238.67 + d -z+b-1459.98
4778.69 +d-z+b
