Maths 2021

              

     N + =15 

    (N +6) + ( -6 ) =15 + (-6) 

     N = 9  

          3n = 9 

          3n  = 9 

          3       3     

            N=3


 3n + 2= 14 

(3n +2 ) + ( -2 ) =14 + (-2) 

n=4


          

        4n - 2 =18 

(4n-2) + 2 =18 +2  

n=5


  

     

n=2 .6 

n=12 



(3n+3.4) 6 = 15 

(3n+12)-6=15 

N =3

    Hi Latiana,
    Well done on solving these math problems. Did you enjoy trying to work them out? Once you continue practising, it becomes a lot easier. Are you having fun with maths whizz and extra maths too? Keep up the great work Latiana and I look forward to seeing you tomorrow. P.S. Could you please include your task description. :-)
