Answer: option D
Step-by-step explanation:
step 1: take 7-3(both have the variable x) and subtract it.
-a- -b= subtract then write the greater no.s sign
+a- +b= if the 1rst number is greater than the second, subtract and give
or make it a positive integer. if the 1rst no. is smaller than the second,
subtract then write the greater number's sign.
step 2: As 2-2 is 0, 2y-2y is 0
step 3: and the sum of the both: is 17-14= 13
