Try using PEMDAS first. Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction

So, first you would do (7-4) and you would get 3 from that.
Liv1234
  • Liv1234
And then you would do 2*3 and what do you get from that?
Ashsmashum1290
  • Ashsmashum1290
6
Liv1234
  • Liv1234
Good! Then you would do 2+9 which is?
Ashsmashum1290
  • Ashsmashum1290
11
Liv1234
  • Liv1234
Good! Now you add 6+11 and what does that add to?
Ashsmashum1290
  • Ashsmashum1290
17

  • Liv1234
Awesome! Was this a multiple choice question?

no i have to write how to simplify this expression
Liv1234
  • Liv1234
Okay, so from the steps I gave you, you can say the first thing you did was use PEMDAS. Then you subtracted what was in the parentheses which was (7-4) and got 3. Then you multiplied 2*3 and got 6 and added 9+2 together and got 11, then you added 6+11 and got 17.

what is the soulution to -30 +k=9 @Liv1234
Liv1234
  • Liv1234
Are there any options?
Ashsmashum1290
  • Ashsmashum1290
yes let me put them up
Ashsmashum1290
  • Ashsmashum1290
A-39, B-21, C 39,D 21
Liv1234
  • Liv1234
Okay, one second.
Liv1234
  • Liv1234
B is the answer. Because if you add -30+9 you get -21 and if you subtract -21 from -30 you get 9.
