X=(y)/(y-3) make y the subject

Liula [17]

Answer:

$\displaystyle y=\frac{3x}{x-1}$

Step-by-step explanation:

<u>Solving Equations</u>

We have the expression:

$\displaystyle x=\frac{y}{y-3}$

And it's required to make y the subject.

It can be done by isolating y on the left side of the equation and the rest of the expression on the right side.

The first step is removing the denominator by multiplying both sides by y-3:

$\displaystyle (y-3)x=(y-3)\frac{y}{y-3}$

Simplifying the right side:

$\displaystyle (y-3)x=y$

Remove the parentheses:

$yx-3x=y$

Move the y's to the left side and the rest of the expression to the right side:

$yx-y=3x$

Factor out y:

$y(x-1)=3x$

Divide by x-1:

$\mathbf{\displaystyle y=\frac{3x}{x-1}}$

Nastasia [14]

Expand the left side:

(3x + 2) (5x + 1) = 15x² + 10x + 3x + 2 = 15x² + 13x + 2

Then a = 15 and b = 13, so a - b = 2.

How much will the monthly payment be for a new car priced at $14,350 if the current finance rate is 36 months at 3. 16%? Include

expeople1 [14]

The monthly payment for the new car is; Choice A; $279. 03

<h3>Percentages</h3>

After the down payment of 30% and financing the 8% TT&L is made; it follows that;

The rest of the payment is;

$14,350(1 - 0.38)

$14,350(0.62)

Hence, $8,897 is the payment made over the course of the duration at a finance rate of 3.16%.

Ultimately, the monthly payment is; $8,897 × 0.0316 = $279.03
