10y−(5y+3z)=? 10y-(5y+3z)=\text{?} 10y−(5y+3z)=?
First, we open the parentheses and change the sign accordingly.
Since there are only positive numbers inside the parentheses, multiplying by the minus will give us negative numbers:
10y−5y−3z= 10y-5y-3z= 10y−5y−3z=
Now we group the Y factors:
10y−5y=5y 10y-5y=5y 10y−5y=5y
Now we obtain:
5y−3z 5y-3z 5y−3z
