Help! Is this correct? If not can i please have a correction?

The answers are correct, however in the first box it should be 22y instead of just 22. Same with the 6 it should be 6x.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
