Question

For what value of the variable: is the value of 9−y twice as much as the value of y?

Answer 1

Answer:

y = 3

Step-by-step explanation:

9 - y = 2y

  + y    + y      Add y to both sides

9 = 3y            Divide both sides by 3

3 = y              When y = 3, the value of 9 - y is twice the value of y.
