Answer 1

First we need to find the number they started with.
(x+7)*2=26

Solve for x
x+7=13
x=6

To do the operations in reverse, we double it first and then add 7.
6*2=12
12+7=19

Final answer: 19

Answer 2

So first, you would take half of 26 since Matt doubled the result giving you 13. Then, subtract 7 which is 6.

For Tikka she did the opposite so take the 6, double it making 12, and then add 7 to get 19.

So the answer would be 19.
