6-74.

Are the following expressions equivalent? Homework Help ✎

3(4

*x*− 2) + 8 2(6*x*+ 1)

Substitute 1 for *x* into both expressions.

3(4(1) − 2) + 8 = 3(4 − 2) + 8 = 3(2) + 8 = 14

2(6(1) + 1) = 2(7) = 14

Now substitute 2 for *x*.

3(4(2) − 2) + 8 = 3(8 − 2) + 8 = 3(6) + 8 = 26

2(6(2) + 1) = 2(12 + 1) = 26

You can try other values for *x*. It appears they are the same.
