Question

PLEASE HELP! I don't get it

Answer 1

Subtract to eliminate y

Explanation:

it is the easiest to eliminate first since 7y and -7y are opposites.

I'm guessing this is one of those problems where u find both y and x .... but yeah its the 3 option

Answer 2

Option 'C i.e. Subtract to eliminate y' is the correct option.

Explanation:

Given the system of equations

-6x + 7y = -54

-7x + 7y = -56

The first step we need to do is to subtract to eliminate y, because 7y and -7y will cancel each other.

`-6x + 7y = -54`

`-`

`\underline{-7x+7y=-56}`

x + 0y = 2

x = 2

Therefore, we get x = 2 after we implemented the fist step to subtract to eliminate y.

Hence, option 'C i.e. Subtract to eliminate y' is the correct option.
