Use substitution to find the solutions for each system of linear equations .

1. Y = -3x

-6x + y = -9

The given linear equations are:

y = - 3x                             (1)

and - 6x + y = - 9             (2)

We have to find, the value of x and y are:

Solution:

Put y = - 3x   in equation (2), we get    

- 6x - 3x = - 9

⇒ - 9x = - 9

⇒ x = 1

Put x = 1 in equation (1), we get

y = - 3(1)

⇒ y = - 3

∴ x = 1 and y = - 3

Thus, the values of x and y are "1 and - 3"

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
