Help me with this problem?

OpenStudy (jravenv):

Vocaloid (vocaloid):

multiply both sides by 4 first, what do you get?

OpenStudy (jravenv):

12

OpenStudy (jravenv):

and I don't know what the other would be

OpenStudy (anonymous):

COMEBACK!!!!!!!!!!!

Vocaloid (vocaloid):

what happens when you multiply (y/4) times 4?

OpenStudy (jravenv):

you get y right?

Vocaloid (vocaloid):

yes so, what do you get when you multiply (y-1)/2 by 4?

OpenStudy (jravenv):

-2(y-1)?

Vocaloid (vocaloid):

not quite, check your sign

OpenStudy (jravenv):

Which one?

Vocaloid (vocaloid):

the first sign

OpenStudy (jravenv):

2(y-1)

Vocaloid (vocaloid):

correct! so put them together: y - 2(y-1), now distribute the 2

OpenStudy (jravenv):

y-2y-1

Vocaloid (vocaloid):

not quite, check the last sign

OpenStudy (jravenv):

y-2y-3?

Vocaloid (vocaloid):

also, check the last number

OpenStudy (jravenv):

y-2y-2

OpenStudy (jravenv):

Sorry my brain is mathed out xD

Vocaloid (vocaloid):

check the last sign what is (-2)*(-1)?

OpenStudy (jravenv):

2

OpenStudy (jravenv):

Ohh so you want it like y-2y+2?

Vocaloid (vocaloid):

yes, y-2y+2 the sign is important! anyway, you can rewrite y-2y+2 as -y+2

OpenStudy (jravenv):

-y+2 okay what's next?

Vocaloid (vocaloid):

Vocaloid (vocaloid):

what happens when you add y to both sides and subtract 2 from both sides?

OpenStudy (jravenv):

Y> 10 ?

Vocaloid (vocaloid):

now look at your answer choices....

Vocaloid (vocaloid):

also, check which direction your > sign is pointing

OpenStudy (jravenv):

That's an answer! Thank you! You're my favorite, you're one of the few who actually explains and lets me do the work at the same time thank you

Vocaloid (vocaloid):

your answer is wrong, check which way the < sign is pointing

OpenStudy (jravenv):

So Y < 10?

Vocaloid (vocaloid):

yes, do you understand why?

Vocaloid (vocaloid):

also, check your sign on 10

OpenStudy (jravenv):

Because when you multiply a negative you have to swap the directions. so it's y<-10

OpenStudy (jravenv):

right?
