Hi there! :)

<u>Answer:</u>

The good answer is the top left one, which is:

2x -1(5 - 3x) = 4x +2

2x - 5 + 3x = 4x + 2


Step-by-step explanation:

2x <u>- 1</u>(5 - 3x) = 4x + 2

The correct first step is to distribute the "-1" to the entire parentheses:

-1 × 5 = <u>-5</u>

-1 × -3x = <u>3x</u>

Once this first step is done, you are left with an equation looking like this:

2x - 5 + 3x = 4x + 2

Which is the top left answer for you!


There you go! I really hope this helped, if there's anything just let me know! :)
