1) Given equation: x/5 + 9 = 11
2) Subtract from both sides of the equation 9 (use Subtraction Property of Equality):
x/5+9-9=11-9,
x/5=2.
3) Unknown variable is dividend, 5 is divisor and 2 is quotient. To find unknown dividend you should find the product of divisor and quotient or in another words use the Multiplication Property of Equality:
x=5·2,
x=10.
These three consecutive steps show you that correct choice is B.
Answer: correct choice is B.
