Question

ALL YOU AMAZING MATHEMATICIANS I NEED YOUR HELP!!!!!!!!

Answer 1

Explanation:

40x + 35x-28 = 75x - 28

40x+35x + -32x - 28 = 84xx - 28

40x - 28

40x + 35x + 32+ 28 = 75x + 60

8x X 5x=40x

8x X -4 = -32x

35x= 7x X5x

7 X -4 = -28

40x - 32x + 35x - 28

75x- 32x = 43x-28

I am pretty sure its the 3rd 1
