Can someone explain how to do this?

Answer: ok ima try my best
the numbers that's in the {} are the umbers you put in for x so
10+10=22 is false
12+10=22 is true
in the x columns you put in the numbers
in the columns with the (x+10=22) you input the number for x so just rewrite it
then you answer if its the answer or not
Step-by-step explanation:
10+10=22 is false
12+10=22 is true < this one is the only one that's true the rest are false
i hope this helps
