I need 100% on this quiz!
The sum of two numbers is 44. The second number is 4 less than three times the first number. Let x represent the first number and let y represent the second number. If the table will be used to guess and check, what should the equation be at the top of the last column?

1. y=3-4x

2. y=4x-3

3. y=4-3x

4. y= 3x-4

(2,5)

Step-by-step

Since we are given

y

=

4

x

−

3

we can substitute this into the other equation and solve for x.

add 6 to both sides and simplify.

10

To solve for x, divide both sides by 5

⇒

x

We can now substitute x = 2 into y = 4x - 3 to find y.

x

Step-by-step explanation:

3 times the first number = 3x

4 less than 3 times the first number = 3x -4

y = 3x -4

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.

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
