I need help with 1-6 its algebra and i don't under stand it that well. Where it says 3,4 and 5 were not suppose to do those ones on the top left side of the paper. Where it says number 1 on the top right side and going down those are the ones we need to do.

Answer 1

give me one second to put them up

Answer 2

This is what i need to do

Answer 3

This is the math problems

Answer 4

Let's start with number 4.
You solve for p by isolating it.
So you first need to multiply by r on both sides to get 2mr = p-q
then move q to finally isolate p
2mr + q = p

Answer 5

For number 3, just check step by step, did they 'move' terms (add/multiply the same thing to both sides) correctly
