Question

Simplify the following problem using the distributive property: 3x+4y+3(x-y)-4x
Show each step in your calculations. Justify each of your steps using number properties. (make sure to name each number property)

Answer 1

you need to distribute the 3 to (x-y), or multiply 3 times (x-y) then group like terms and simplify

Answer 2

could you explain a little further please?

Answer 3

3x+4y+3x-3y-4x By the way. Does all this equal zero in the original problem?

Answer 4

ooh okay i see. It doesn't say what it equals out to so i am not sure. What number property did you use to get 3x+4y+3x-3y-4x?

Answer 5

distributive, basically you are distributing the 3 to the x and -y...one for you, and one for you... lol

Answer 6

ooh haha okay. What would be the next step?

Answer 7

well if you were supposed to solve for a variable or something you would need it to be equal to something. If it equaled zero to begin with you could add all the x terms and all the y terms....2x+y=0? then y=-2x

Answer 8

okay...got it, im pretty sure thats what it is asking to do. so what property would those be then?

Answer 9

hello hello? can someone please help? D: i need to know what the last couple number preopertys are!
