First, you would have to get the Y all on one side of the equal sign. You would do that by adding the 10Y and -4Y together.

10y+10 = 4-4y
+4y +4y

So now you have 14y on one side, and 0y on the other.

14y+10 = 4.

You still have the +10 on the 14y's side. Like I said, your main goal is to get Y by itself. So you subtract 10 from both sides.

14y+10 = 4
-10 -10

Now you have 14y on one side, and -6 on the other.

14y = -6.

Y is still not by itself. You 14y means 14 * (multiply) y. What is the opposite of multiplying? Dividing. So you divide 14y by 14 to get y all by itself. Then you divide -6 by 14 on the other side.

14y = -6.
/14 /14

Now you get your final answer of y = -6/14. Reduce the fraction.

y = -3/7. << That is your final answer.

10y + 10 = 4 - 4y
10 = 4- 4y - 10
10y + 4y = 4 - 10
14y = 4 - 10
14y = -6
y = -6/14 = -3/7

Subtract the 4 on the right side from the 10 on the left side. Your left with 10y-6=-4y
Now subract the 10y from the -4y and your left with:
6=-14y
Now divide -14 from the 6 so the answer is ( so "y" equals):
as a fraction: 6/-14 or simplified to -3/7
as a decimal: -.4285714286 as far as my calculator goes but I would round it

10y+10=4-4y

14y = -6
7y = -3
y = -3/7

10y + 10 = 4 - 4y
+ 4y on both sides so,...
14y + 10 = 4
- 10 on both sides so,...
14y = -6
Divide 14 on both sides so,...
y = -6/14 = -3/7

First you bring 4y to the left, which will give you 14y. Then subtract 10 from both sides, which will give you -6 on the right side. then divide 14 on both sides, giving you -6/14, which you can simplify to -3/7.

Combine like terms....10y+4y=4-10

Do you understand why the signs changed?

This is basic algebra, you should grasp this concept or it will only get harder.

No offense but you really need to try and do your own homework. But I must say this is a very good idea.
