Answer 2

any ideas on what to do?

Answer 3

a few

Answer 4

let me here them

Answer 5

you add them somehow to get your answer

Answer 6

youve got the right idea, lets make it more sound tho

if we have 2 things that are the same, they are equal .... then we want to keep them equal. whatever we do to one side we have to do to the other.

on one side we have -4.8 + x, but we only want the x part .... if we add 4.8 to it will that get rid of the extra numbers?

Answer 7

-7.12 = -4.8 + x
+4.8 +4.8
-----------------
?? = 0 + x

Answer 8

if we estimate, then the solution is about -7+5
