@Joshiscool what is the first step we should take to solve this equation? :)

Answer 7

The first, and in this case the only one, is to do reverse order of operations to isolate the variable

So what would the first step be?

Answer 8

IDK

Answer 9

Ok, so first we want to isolate y.
Do you know how to do that? :)

Answer 10

Well if you have to do reverse order of operations then you would have to do the very last step of order of operations right?

Which is addition/subtraction

What could you add or subtract to isolate the variable?

Answer 11

Maybe the answer will tell me all by it's self and maybe I can give out medals to the one who tells me first

Answer 12

....

Answer 13

yeah no

Answer 14

cant you just subtract -6.3 from -2.2

Answer 15

We're not allowed to give out direct answers, sorry.

Answer 16

Yup Ashely14 got it

Answer 17

i didnt give out a direct answer

Answer 18

But remember not just from the -2.2 but you have to subtract from both sides
Yeah dont worry thats not direct

Answer 19

okay

Answer 20

I got 8.5

Answer 21

so if you subtract them both you will get -4.1

Answer 22

i think

Answer 23

y−6.3=−2.2
add 6.3 to both sides.
y−6.3+6.3=−2.2+6.3
y=4.1
Was thAT HELpful, Josh you need to understand The steps,

Answer 24

I added then I subtracted and I got the same number both times

Answer 25

You made mistake in adding or maybe while you where subtracting

Answer 26

I think another way he could do it is by (-6.3)-(-2.2)= -4.1
