Can someone explain how i do 5 through 10? i’m a bit confused on how to do them.

when you put a number in front of an equation then it applies to every element in that equation.

here we are balancing equations, you need to make sure that each side has the same number of elements. please ask for more help in the comments if you have another question. i am happy to help with this
