Question

Which expression is equivalent to 3y?

a) 3vx + 12 - 12
b) &x + 3 + 3
c) By + 2(x + 12) - 2
d) 36 - 1

Answer 1

The expression that is equivalent to 3y is option C) By + 2(x + 12) - 2.

Step-by-step explanation:

The expression that is equivalent to 3y is option C) By + 2(x + 12) - 2.

Let's break down this expression to see why it is equivalent to 3y:

By + 2(x + 12) - 2 = By + 2x + 24 - 2 = By + 2x + 22

Since there is no coefficient in front of the y (i.e., the coefficient is 1), the expression By can be simplified to just y. So, the expression becomes 2x + y + 22, which is the same as 3y.
