Answer:
2*2/4, 6*6/36
Step-by-step explanation:
Saying "a number" is the same as saying "x"
"Three more than a number" is the same as "three more than x"
If you have three more of something (say, marbles) than someone else, then you have their number of marbles plus three more.
Then, "Three more than x" is the same as "three plus x", or "3 + x"
Hope this helps! :)
