What do you get when you subtract 4 from 34?

Answer 5

0 and 30

Answer 6

Okay, this transforms the equation...

-5x + 4 = 34

Becomes

-5x + 4 - 4 = 34 - 4

-5x + 0 = 30

or just

-5x = 30

What do you suppose we should do next?

Answer 7

ummmm do something with numbers, haha! idk

Answer 8

Not good enough. You must get 'x' all by itself. What is it that is now the problem with that goal? Is 'x' all alone?

Answer 9

do we multiply the 5 and 30? or add?

Answer 10

How is the "-5" attached to the 'x'. What operation is implied by writing "-5" and 'x' next to each other like that?

Answer 11

uhhh, okay sorry I don't know, that's why I'm on here. I suck at math!
