Hey there!
In order to simplify the first expression, we need to use the Distributive Property:
4(7x-4)=28x-16 (the same as 4*7x-4*4)
Hence, the equivalent expressions are


In order to simplify the second expression, we need to combine like terms:
11y+3y+9y
11y+12y ✓
23y ✓
Hence, the equivalent expressions are

Hope everything is clear.
Let me know if you have any questions; if so, please comment.
