Question

Which of the following equations could be the result of using the comparison method to solve the system shown? x - 4y - 1 = 0 x + 5y - 4 = 0

4y + 1 = 4 - 5y
-4y + 1 = 4 - 5y
4y + 1 = 5y - 4

Answer 1

number 1:

4y +1 = 4 - 5y

Answer 2

Option A.

Explanation:

The given system of equations is

`x-4y-1=0`

`x+5y-4=0`

The given equations can be rewritten as

`x=4y+1`

`x=4-5y`

Using comparison method, compare the values of x.

`4y+1=4-5y`

Therefore, the correct option is A.
