The solution of the equations is (-2, -1)

<h3>System of equation:</h3>

2x - 3y = -1

11x  - 9y = -13

Using elimination method let multiply the first equation by -3.

Therefore,

-6x + 9y = 3

11x - 9y = -13

5x = -10

x = -10 / 5

x = -2

let's find y as follows;

2(-2) - 3y = -1

-4 - 3y = -1

-3y = -1 + 4

-3y = 3

y = 3 / -3

y = -1

2. Rich wrote a novel that sells for n dollars each. He received a bonus of $50,000 to sign the
Yuki888 [10]

The equation which represent total amount of income he earns from selling book is,  A=50000+\frac{109}{100}bn

Since, Selling price of one novel is n dollars

So, selling price of b books is,  n*b=nb

Since, he receives 9% commission on each book sale.

So, total commission he receives on selling of b books is,

                                      nb*\frac{9}{100}=\frac{9}{100}nb

And  also he received a bonus of $50,000 to sign the  contract to write the book,

So, total amount of income he earns is represented by A,

                  A=50000+bn+\frac{9}{100}bn\\\\A=50000+\frac{109}{100}bn
