If you divide a number into 3 equal groups and then divide each group in half, you end up with 13. write an equation to express the situation. then, determine what number you started with?

x  = 26

Step-by-step explanation:

Let   x  b the number

then x/3   (we divide x in three equal gups)

And then each group is divide in half

You end up in 13  s we have

x/3  +  X/3/2   =  13

x /3   +  x/6    = 13

(2x  + x  )/6     = 13

2x  +  x   = 78

3x   = 78

x  = 78/3

x  = 26
