Bradley and Ryan are having a contest to see who can collect the most bumper stickers. Bradley started with 23 bumper stickers and plans to add 4 each month. Ryan has 9 bumper stickers and plans to add 6 each month. After how many months will they have the same number of bumper stickers? My work: 23+(7)x4=9+(7)x6 23+28=9+42 51=51

    You can draw a quick draw to find the solution to this as well. You have one equation being y = 4x + 23 and the other being y= 6x + 9. If you equate the two you get 4x + 23 = 6x + 9. Now solve this for x.
