Question

3y-5(y-1)=-5 how can I solve this

Answer 1

what are your thoughts about how it can be solved?

Answer 2

Well at first I thought solve the one in the perentheseis but I keep getting it wron

Answer 3

your onthe right track..

Answer 4

Try distributing the 5 through to each term in the parens, then combine like terms and move the constants to one side and the variable term to the other.

Answer 5

lets distribute that -5 thru the paranthesis like this:

3y -5y +5 = -5

now what can we do?

Answer 6

So do I subtract the 3y with the 5y

Answer 7

you do...

3y -5y = -2y right?

-2y +5 = -5 this looking like something you can solve yet?

Answer 8

i keep getting 6.

Answer 9

6 as an answer to the problem?

Answer 10

-2y +5 = -5....what can we do next?

Answer 11

Thats where I am stuck at. The whole = part confuses me.

Answer 12

with a basic equation such as this, they want you to become strong in your basic properties of addintion and multiplication. these foundations are what we use in all the other higher orders of math. if you dont have a firm grasp of it now, its gonna hurt you in the future :)

Answer 13

Yes, I agree. Its hurting me now. I am a college student and its extremely hard

Answer 14

lets see if we can do the simple step here and I will see if I can explain what we did with that -5 later ok?

-2y +5 = -5

we have a balanced equation here. whatever we add to one side has to be added to the other to keep it equal, balanced

Answer 15

Ok

Answer 16

Remember that because each side equals the other, you can maintain equality by doing the same thing on both sides. If we want to isolate (get by itself) the term with the y, we can subtract 5 from both sides.

Answer 17

what happens when we add (-5) to both sides?

-2y +5-5 = -5-5

-2y +0 = -10

-2y = 10 you with me so far?

Answer 18

-2y = -10. I missed that negative on there sorry.

Answer 19

Oh ok

Answer 20

now to get y all alone, we need to divide it by (-2) why? becasue -2/-2 = 1

-2y/-2 = -10/-2

1y = 5

y = 5

Answer 21

Oh. I see. Thanks a mill

Answer 22

noprob :)

Answer 23

Thats was easier than I thought. I was looking too much into it.

Answer 24

alot of people do, they get nervous with it and what really happens with math is you know HOW to do it, but are afraid to be wrong in the end :) at least thats how I feel alot

Answer 25

Thats right. Well thanks you I aprreciate your help.
