Math help!??!?!?!?!?

Question

Find number replacements for a and b so that a b=16 and a-b=2? Help- I've been trying for hours and can't get it...

Answer 1

Jo has it right.

Multiples of 16:

1x16

2x8

4x4

-1x-16

-2x-8

-4x-4

then plug it in

-4 - -4 = 2

the answer is

a=-4 and b=-4

Answer 2

can you make sure you got that right?

Answer 3

a=9

b=7

Answer 4

a+b=16

b=16-a.  (Just rewrite the problem)

a - (16-a) = 2

a-16+a=2

a+a=18

2a=18

a=9

Therefore,

9+b=16

b=7

Answer 5

Is that ab=16 ?

if so i would list out the multiples of 16

1x16            now take the multples subtract them until you get 2

2x8                   none of these do so......

4x4

-2x-8

-1x-16

-4x-4

maybe im doing it wrong
