Solve and show work please :( (3x + 10) - 5x = 6x -50

hero (hero):

1. Remove the parentheses from (3x + 10). Let me know what you get.

hero (hero):

@millecityy_

OpenStudy (anonymous):

what do you mean remove parentheses? It'll just be : 3x + 10

hero (hero):

Yes, exactly, but show me what the entire equation would look like afterwards.

hero (hero):

Anyway, the equation would look like 3x + 10 - 5x = 6x - 50 2. Next, subtract 10 from both sides. Let me know what you get.

OpenStudy (anonymous):

Im stuck

hero (hero):

All you have to do is subtract 10 from both sides. How did you get stuck?

OpenStudy (anonymous):

Subtract from where? I'm confused

hero (hero):

|dw:1346007512268:dw|

OpenStudy (anonymous):

So the left side is -40? and the right is 0?

hero (hero):

When someone says, "subtract a number from `both sides`, they mean for you to subtract the number from `both sides of the equal sign`.

OpenStudy (anonymous):

That's what I did, I think?

hero (hero):

But your result should look like this: |dw:1346007900087:dw|

OpenStudy (anonymous):

I just did it but i reversed it. Thank you

hero (hero):

Yes, but what I mean is, when you write the result back to me, you should write out the result you got which should have been `3x -5x = 6x - 60`

hero (hero):

Do you want to finish this or not?

hero (hero):

@millecityy_

OpenStudy (anonymous):

Yes i do

hero (hero):

Okay, so next, subtract 6x from both sides

OpenStudy (anonymous):

66?

hero (hero):

Not exactly: |dw:1346008518597:dw|

OpenStudy (anonymous):

1 and 0?

hero (hero):

You're supposed to let me know what the result of your subtractions were. I can't help you unless you let me know what the entire equation looks like after your subtractions.

OpenStudy (anonymous):

Im asking if that's right? I would get 1x from subtracting -5x - -6x
