Question

Can someone help me out with this problem and tell me how to do it :D

Answer 1

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
