Answer 5

You're welcome

Answer 6

DId she guess?

Answer 7

@kenna_098 may just suck at maths!

To solve this question:

subtract 3.4 from each side of the equation and then you can simplify to get the answer

Answer 8

Thats rude. But okay.

Answer 9

I didnt guess... all you had to was subtract 3.4 from both sides
It cancels out on the left side so on the right side of the equal sign you subtract -6.85-3.4
You end up getting -10.25
That means it is answer A
That means that I am correct
That also means that you are wrong because there is no simplifying involved!!!

Wow your smart

Answer 11

But please guys don't fight

Answer 12

The point I am making is that if you just give the answer then the poster has NO WAY of knowing whether you have any idea about how to do the question.

MANY answers here are just plain wrong.

you 'simplified when you completed the subtraction:

3.4+y= -6.85
3.4+y-3.4 = -6.85-3.4
SIMPLIFIES TO
y= -10.25

Answer 13

subtracting isn't simplification
-10.25 is the answer you get from subtraction

Answer 14

giving the answer simply shows that YOU know how to do it - it doesn't help the poster to understand or learn anything

Answer 15

I did show how I did it... In the first comment I showed my answer then in the next comment I explained how I got my answer @MrNood
