Answer:

x = -12

Step-by-step explanation:

Remember that ax + bx = (a+b)x

-10x + 9x = 12

Add -10x and 9x together

(-10 + 9)x = 12

-x = 12  (-1x is written as -x, just as 1x is written as x)

÷ -1 both sides

x = -12

I hope this helps. Happy studying. :)

Finally, suppose you decide not to finance (get a loan for) the car and to
Alexxandr [17]

<u>Supposing a cost of $30,000</u>, and using proportions, it is found that you would have to save $1,083.30 each month.

--------------------------

  • We suppose a cost of $30,000.
  • You already have $4,000 saved.
  • 30 - 4 = 26, thus, you would need to save $26,000 in 2 years = 24 months.
  • How much per month?

We can solve it using proportions, by the following rule of three:

1 month - $x

24 months - $26,000

Applying cross multiplication:

24x = 26000

x = \frac{26000}{24}

x = 1083.3

You would have to save $1,083.30 each month.
