Simplify `(k+3) - (3k - 5)` .
Equivalent to: `1(k+3) -1(3k-5)`
Use the distributive property:
`k + 3 -3k + 5`
`k-3k + 3 + 5`
` ``-2k +8`
or `-2(k+4)`
The solution is -`2k+8` or `-2(k+4)` .

To simplify `(k+3)-(3k-5)`
Multiply `-1` by each term inside the parentheses.
`k+3+5-3k `
Since `k` and `-3k` are like terms, add `-3k` to k to get `-2k` .
`-2k+3+5`
Add `5` to `3` to get `8` .
`-2k+8 `
Reorder the polynomial `-2k+8` alphabetically from left to right, starting with the highest order term.
`8-2k`

To simplify the expression `(k+3)-(3k-5)` , first we need to remove the parenthesis:
`= (k + 3) - (3k-5)`
`= k + 3 - 3k + 5`
Combine like terms.
`= 3 + 5 + k - 3k`
`= 8 - 2k`
Check if the resulting equation is factorable. In this case, it is factorable by 2. Factor out 2.
`= 2(4-k) ` -> answer

QUESTION:-
How do I simplify (k+3)-(3k-5)?
SOLUTION:-
(k+3) - (3k-5)
In order to solve this problem; we open up the brackets by multiplying each component of the second bracket with the minus sign:
= k + 3 -3k + 5
= k - 3k + 3 + 5
= -2k + 8
Or there is yet another way that this question can be further simplified;
= 2 (-k + 4) OR = -2 (k - 4)
Hence Solved

(k + 3) - (3k - 5)
To simplify this we can follow the rule of BODMAS or PEMDAS. First we have to remove the brackets,
k + 3 - 3k + 5
- 2k + 8
It cannot be simplified further so we factor out the above,
- 2k + 8
- 2(k - 4) Answer.

(k+3)-(3k-5)
distribute negative
k+3-3k+5
combine like terms
-2k+8 factor out
-2(k-4)

(k+3)-(3k-5)
the answer would be -2k+8 because all you do is subtract the ones with k and the regular numbers following your negative rules.
you can simplify this to 2(-k+4)

(k+3)-(3k-5)
k+3-3k+5 combine like terms
k-3k=-2k
3+5=8
-2k+8 is the answer or find the GCF
-2(k-4)
