This one i'm really confused on because i do not know if it is -5m

Answer 1

what do you mean "do not know if it is -5m" ?

Answer 2

Because it says 17 - 5m i do not know if it meant as a -5m or 5m

Answer 3

It means
"17 minus 5m"
However, it can also be read as
"17 plus negative 5m"

Answer 4

First step. Let's move the 3m to the left side

Answer 5

What is the opposite of 3m?

Answer 6

-3m

Answer 7

correct. so you would subtract 3m from both sides of the equation
17 - 5m = 20 + 3m
- 3m - 3m

17 - 8m = 20 + 0

17 - 8m = 20
What now?

Answer 8

do the opposite of subtraction

Answer 9

umm...not really. You want to move the 17 to the other side. How do you do that?

Answer 10
