    • @aidang4070
      @aidang4070 2 года назад +2

      the multipled by three so that it would match up with the other y which is 3y so it could cancel out. SOrry if it isn't well explained

    • @imzack1275
      @imzack1275 Месяц назад

      It's so that we can cancel the y value in the joined equation so we can solve for x and find y later.. 3y and -3y cancel out

  • @roccocoa

    On the last problem, i got x as -47/11 and y as 63/11. When substituting into equation 1, it came out as 33 so im confused

      You can maybe try talk to a teacher or something to help you
      Maybe try get an app or something that can also explain it to you more easily?
      Maybe try search for another video?

    Base on what I've learned this isn't correct or maybe it's just different numbers that u used than what I used. Cause I used 2 and 3 to get the coefficients to be equal numerically

      Because they got the value of y in the first equation which is 3 so instead of writing y with the first equation they multiplied by 3 aka the value of y
