Simplify the following expression using the distributive property: 2x – 3y + 4(x – y) + 5x What property do I use after the distributive?

    can you do the distributive part first?

    2x – 3y + 4(x – y) + 5x What you you get after you apply the distributive property to 4(x – y)?

    but after that what property do I use? commumative, associative?

    you literally just pick up term and move it. Like moving blocks on the floor when you were a kid. Let's say you had blue, red, yellow block. in that order, but you wanted red before blue, so you pick up the red block and move it in front of the blue or you pick up the blue bock and put it behind the red. Make sense? Now your blocks are terms (+4x or -4y etc) Just move them like you would blocks

    this is your equation : \[2x – 3y + 4(x – y) + 5x=2x – 3y + 4x –4 y + 5x\] Now starting from there. Move the +5x to a better spot
