A boy works out the (x+y ) number of sums of which only (y-2z) sums are right. How many are wrong? (a kind request to my followers ｡⁠◕⁠‿⁠◕⁠｡

Step-by-step explanation:

Total sums solved = x+y

Sums solved correctly= y-2z

Sums solved incorrectly=?

Total sums solved = Sums solved correctly+ sums solved incorrectly

Sums solved incorrectly= Total sums solved - Sums solved correctly = x+y -(y-2z)

= x+y -y +2z = x+2z

So, he did x+2z questions wrong...
