Since they decided to be extremely ridiculous and deleted my answer for "not showing enough work", here I am again:
Since it says that Kiwi is 13 less than TWICE Granny's age, I divided 77 (Granny's age) by 2, which gave me 38.5
I then subtracted 13, since it says that she is thirteen less than that number, which gave me 25.5
I had originally said "20 or 20 and a half years old" because depending on your format of testing/worksheet, you may not have the option of putting halves.

Answer:
(x, y, z) = (x, x+2, 3x+1)
Step-by-step explanation:
We can add twice the second equation to the first to get ...
[eq4] -3x +0y +z = 1
Adding the first and second equations gives ...
[eq5] -x +y +0z = 2
Solving [eq4] for z gives ...
z = 3x +1
Solving [eq5] for y gives ...
y = x +2
Then the solution triple is (x, y, z) = (x, x+2, 3x+1).

Hello!
We can double check by plugging in 26 back into x
And it works out!
