To simplify (2a+3b-2) - (5a-2b+3c) you distribute the negative sign inside the parentheses of the second expression and then combine like terms:
(2a+3b-2) - (5a-2b+3c)
= 2a + 3b - 2 - 5a + 2b - 3c
Now, combine like terms:
= (2a - 5a) + (3b + 2b) + (-2 - 3c)
= -3a + 5b - 2 - 3c
So, (2a+3b-2) - (5a-2b+3c) simplifies to
( -3a + 5b - 2 - 3c ). Hope this helps
