2х - Зу = 165x - Зу = 13​

Mathematics
1 answer:
Alex787 [66]3 years ago

Answer:

[-1, -6]

Step-by-step explanation:

Since both coefficients next to your <em>y</em><em>'</em>s are identical use the Elimination Method by multiplying one of the equations by -1 to form <em>additive </em><em>inverses</em><em>,</em><em> </em>meaning they result in 0:

-1[{2x - 3y = 16}]↷

{5x - 3y = 13}

{-2x +<em> </em>3y = -16

{5x - 3y = 13

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

3x = -3 [Divide by 3]

x = -1

y = -6 [plug in "-1" back into both equations to confirm their authenticities]

Value (in billions) 2017 2018
Tomtit [17]

The Owner's Equity for commercial banks in  2017-2018 is $0.4 billion.

The given is,

Borrowings = $0.10 Billion

Owner's Equity = $0.40 Billion

<h3 /><h3>What is the formula for the total liabilities?</h3>

Total liabilities = deposits + borrowings

So we have Borrowings = total liabilities - deposits

Borrowings in 2017

= $14.60 - 11.90

= $2.70 billion

Borrowings in 2018

= $14.80 - $12.20

= $2.60 billion

Borrowings from 2017-2018

= 2.60 - 2.70

= $0.10 billion

Owner's Equity= total assets - total liabilities

Owner’s equity in 2017

= $16.2 - $14.6

= $1.6 billion

Owner’s equity in 2018

= $16.8 - $14.8

= $2 billion

Owner's Equity from 2017-2018

= 2 - 1.6

= $0.4 billion

4x +6y =0
PSYCHO15rus [73]
Here, x - 2y = 14
x = 14 + 2y

Now, substitute this value into first equation, 
4x + 6y = 0
4(14 + 2y) + 6y = 0
56 + 8y + 6y = 0
14y = -56
y = -56/14
y = -4

Substitute it into second equation, 
x = 14 + 2(-4)
x = 14 - 8
x = 6

In short, Your Answer would be: (6, -4)

Hope this helps!
