13-5-13+3a?

Question

I don't understand it

Answer 1

-5+3a

Answer 2

It's a maths problem which you will have to take the signs priorities * / + - to simplify it .

Now , in the problem the first thing you do is to take each two number from the let to the right

1- 13-5 = 8 , hence , 8-13+3a
2- 8-13 = -5 , hence -5+3a
Thant would be your final answer of this question , Unless the question was 13-5-13+3a = 0 that's another question.

Answer 3

Ok, this is an expression. It isn't an equation because there is no "=" and a value on the other side of it. To simplify it,(which is probably what you need to do), you simplify like terms. Like terms would be things like (13, -5,-13 or 3a, 5a, 2a) just similar terms.
So, first you organize it so that the variable(3a) is in the front and the constants(13,-5,-13) are in the back.
3a+13-5-13.
Since there aren't any other like terms for 3a you just leave it there and simplify the constants:
3a+8-13
And simplify again:
3a-5

Answer 4

*Ok, so what you first do, is go from right to left.
So, you do 13-5. Your answer will be 8.
**Then you get 8-13.
And your answer here would be -5.
So you get -5+3a as your answer.

Answer 5

5/3=a

Answer 6

13 substrt 5 subtract 13 and add 3 a

Answer 7

-5+3a

Answer 8

-5+3a

Answer 9

13-5= 8
8-13= -5
-5+3= -2
= -2a

Answer 10

Just simplify it as much as you can...

It reduces to 3a-5
