Simplify: (6y + 10z) - (13y - 5z + 4)
-7y+5z-4
thanks man
It's -7y+15z-4
The reason that it's 15 and not 5 is because the two negative signs become a positive
To simplify the given expression, we need to remove the parentheses and combine like terms.
(6y + 10z) - (13y - 5z + 4)
First, distribute the negative sign to all terms within the second set of parentheses:
= 6y + 10z - 13y + 5z - 4
Now, combine like terms by adding or subtracting coefficients of similar variables:
= (6y - 13y) + (10z + 5z) - 4
= -7y + 15z - 4
So, the simplified expression is -7y + 15z - 4.
