Insert grouping symbols for the following: 5 - 3 x 2 + 8 x 5 - 2; 28 (how did you obtain the answer)?

Question

please explain :) Thanks!

Answer 1

The first two people are wrong. The order of operations is
P arenthesis
E xponents
M ultiplication or
D ivision (whichever comes first in equation)
A ddition or
S ubtraction (whichever comes first in equation)

So, you do this:

5-(3 x 2)+(8 x 5)-2
5-6+40-2
-1+40-2
39-2
37

(note: if the answer HAS to be 28, then they are right. if you need to follow pemdas, then this is right)

Answer 2

a million) commence via dispensing the 7 into (x - 4) 7 • x = 7x 7 • -4 = -28 So, 7(x-4) is an similar as 7x-28 2) distribute the -2 into (x-3) -2 • x = -2x -2 • -3 = 6 So, -2(x-3) is an similar as -2x+6 3) So, 7(x-4)-2(x-3) is an similar as 7x-28-2x+3 4) combine like words 7x + (-2x) = 5x (-28) + 6 = -22 5) So, 7x-28-2x+3 is an similar as 5x-22 6) Isolate x 5x-22=8 a) upload 25 to each and each part, 5x=30 b) divide each and each part via 5, x=6 7) answer: 6

Answer 3

(5 - 3) x 2 + 8 x (5 - 2)
(5 - 3) x 2 + (8 x 3)
(2 x 2) + 24
28

Answer 4

(5-3)2+8(5-2)
2x2+8(5-2)
2x2+8x3
4+(8x3)
4+24
28
