Does anyone know how to do this i am not sure how to solve this !

The first one is the second option because there could be an increase of pay for the same amount of phone usage so you would need further info.

The second one is the 3rd option because for every song downloaded less are being being bought.

The third one is the first option because hitting more baseballs/softballs doesn't mean you will catch less or catch more baseballs/softballs.

The 2nd option im not so sure of tbh thought i might let you know!

Hope this helps out my dude!!

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
