Answer:
make An equation for both of the numbers in the parentheses .
Step-by-step explanation:
this is how it should look x -2 would be x =15, because you add 2 on both sides , now you have x=15 which should be the answer because 15 is now x and 15 minus 2 = 13
now for the second one
first subtract 10 on both sides then you should get the answer X equals three the reason why it’s like that is because 3 is now x and 3 + 10 = 13.
Hope this helped have a good day :D
