In normal mathematics, never.
X=5Y= 92x + 11= ?2(5)+11=?10+11= 21
This is related to an x + (x+1) + (x+2) function, in which case x equals 10. 10+11+12 is equal to 33.
2x-11=10 then 2x=21 so x =21/2
It isn't 2X10 = 20, 2X11 = 22

It isn't 2X10 = 20, 2X11 = 22
XI= 11 because X equals 10 and I equals 1. So take X+I (10+1) and get XI (11)
10 times 11 equals 110 10 x 11=110
10
x+2=11 x+2=-11 x=9 x=-13 x=-13,9
-11
(2, 11)
x = +11 or -11
