Use the definition of subtraction to rewrite the subtraction equation as an addition equation. a) 34 - 6 = x b) x - 64 = 80

help

If 34 - 6 = x then what is x+6 ?

I just need b I did a

Ok well if x - 64 = 80 then what is x ?

is it -64+x=80?

No

Well maybe actually. I'm not entirely sure what the point of this exercise is.

what is it I dont need it solved just need the equation as an addition prob.

Are you supposed to be adding negatives

Or are you supposed to use the equality fact.

Im supposed to use the definiton of subtraction to make x - 64 = 80 as an additon prob....

I can read. I just have no idea what that means.

You can rewrite it as a lot of addition problems.

lol

x + 0 = 144 x + 1 = 143 x + 2 = 142 .... x = 144 + 0 x = 143 + 1 x = 142 + 2 ... etc.

Use the concept of addition to show that 8 > 2. wht about this one?

And that's not even counting the options for doing both..

That's pretty easy.. start by rewriting 8 as the sum of 2 and another number.

Then you can see that it's greater.

thx

im geussing for b they want x+(-64)=80

guessing*
