Answer:
B and C
Step-by-step explanation:
A. y + 11 = 22         →  subtract 11 from both sides:
     y = 11
---------------------------------------------------------------------------
B. 8 = 18 - y           →  subtract 18 from both sides:
     -10 = -y              →  divide both sides by -1:
      10 = y
----------------------------------------------------------------------------
C. 60 = 6y             →  divide both sides by 6:
     10 = y
-----------------------------------------------------------------------------
D.  = 4                  →  multiply both sides by 5:
 = 4                  →  multiply both sides by 5:
    y = 20 
-----------------------------------------------------------------------------
E. 10y = 20            →  divide both sides by 10:
      y = 2
