Answer :
Answer
Options A, C and D are all correct.
They simplify to give 5x - 3y
Explanation
We are asked to pick the expressions which simplify to give 5x - 3y
Taking the statements one at a time,
Option A
5x + -8y + 5y
= 5x - 8y + 5y
= 5x - 3y
This option is correct.
Option B
15xy ≠ (5x - 3y)
This option is not correct.
Option C
5 (x + y) + -8y
= 5x + 5y - 8y
= 5x - 3y
This option is correct.
Option D
-2 (2y - x) + x + x + x + y
= -4y + 2x + 3x + y
= 5x - 3y
This option is correct.
Hope this Helps!!!
