What it is basically asking is if Y = -4, find the value of x in the equation 6x + 7y = 4x + 4y
To solve this you just need to plug in -4 for y and solve for x
6x + 7(-4) = 4x + 4(-4)
6x - 28 = 4x - 16
Now isolate x by adding 28 to both sides
6x - 28 + 28 = 4x - 16 + 28
6x = 4x + 8
and subtract 4x from both sides
6x - 4x = 4x - 4x + 8
2x = 8
divide both sides by 2
2/2x = 8/2
x = 4
x = 4, y = -2
Answer: (4, - 2)
Hope it helps :)

Step-by-step explanation:
f(x)= Quotient × (x+2) + remainder
From this equation we obtain remainder by putting x=2 ( can you see why?)
Hence remainder is f(2)

Answer:
$662.77
Step-by-step explanation:
Data provided in the question:
Amount Mary owes = $750
Discount rate, r = 16%
Time period = 10 months = years = 0.833 years
Now,
Amount Mary owes = Loan Amount × ( 1 + r )ⁿ
or
750 = Loan amount ×
or
750 = Loan Amount × 1.131
or
Loan Amount = $662.77
The amount of the loan she should ask for so that her proceeds are $750 is $662.77
