Exercise 2 Page 40

Determine what each prompt is asking.

6y=24-3x or 24-6y=3x

Practice makes perfect

To begin, let's label each prompt to make discussing them easier.

Name	Equation	Prompt
A	3x+6y=24	Solve for x.
B	24-3x=6y	Solve for x.
C	6y=24-3x	Solve for y in terms of x.
D	24-6y=3x	Solve for x in terms of y.

One Possible Answer

Notice that in the table above, C is the only prompt that asks to solve for y. All others ask that we solve for x. Therefore, C does not belong.

Another Possible Answer

From the table, we can also notice that D is the only equation that shows the x term isolated on one side. Because of this, D does not belong.
