y + 1 + 4 (or y + 5)

6r * 7 (or 42r)

Step-by-step explanation:

The first one you can remove the brackets for completely as there are no negative signs:

y + 1 + 4

Then just collect like terms (1 and 4):

= y + 5

The second one can be re-written like this:

6r * 7

Now you can simply just multiple 6r by 7:

= 42r
